Electrolytes Lab Report

The goal of this experiment is to find out what is the identity of the unknown hydrate? To answer this question first, we should know what a hydrate, and how to identify a hydrate using the law of constant proportions. A hydrate is a pure substance because it contains water molecules embedded in its crystal structure that does not vary. By heating the unknown hydrate, we can calculate the mass of the hydrated, and the percentage of water in the hydrate.

Investigative Question: Does tap water, Powerade or orange juice contain more electrolytes? Hypothesis: Powerade will contain the most electrolytes as millions of Rands are spent on engineering these drinks to rehydrate athletes as effectively as possible. Variables: Independent: Orange juice, Powerade, distilled water, temperature

The purpose of this report is determine if sodium chloride is a viable option as a deicer on winter roads. To determine this, one must compare a multitude of factors. In this lab, the freezing point depression of water, enthalpy of dissolution, cost, and environmental impact will be discussed. A large factor in how effective a substance is as a deicer is it’s ability to decrease the freezing point of water. If the freezing point of water can be lowered, the outside temperature must be much colder to reach this new freezing point, resulting in less ice on the roads.

The lab started off by measuring critical materials for the lab: the mass of an an empty 100 mL beaker, mass of beaker and copper chloride together(52.30 g), and the mass of three iron nails(2.73 g). The goal of this experiment is to determine the number of moles of copper and iron that would be produced in the reaction of iron and copper(II) chloride, the ratio of moles of iron to moles of copper, and the percent yield of copper produced. 2.00 grams of copper(II) chloride was added in the beaker to mix with 15 mL of distilled water. Then, three dry nails are placed in the copper(II) chloride solution for approximately 25 minutes. The three nails have to be scraped clean by sandpaper to make the surface of the nail shiny; if the nails are not clean, then some unknown substances might accidentally mix into the reaction and cause variations of the result.

Sports drinks high in sodium, potassium, magnesium, and calcium can help retain fluids, and proper fluid balance contributes to optimal performance. Sodium is the most important electrolyte to monitor during exercise or play. High losses of sodium, typically through sweat, can lead to muscle cramps, which can lead to decreased performance and possibly more major health complications. Sodium losses in sweat are greater than any other electrolyte. Potassium, along with sodium helps prevent muscle cramps.

I also drink a lot of water, so I am hydrated whenever I need to complete a tough workout or a race. It also shows me what not to eat and drink. I try to stay away from eating too much sugar and I do not drink soda anymore. My coach tells us to watch what we eat and that every little thing you do could be the difference between winning and losing a meet.

Food such as fruits, vegetables, milk and fish / fish rich in potassium is found. Bananas, citrus fruit / citrus fruits and potassium is present in fruits like avocado. Potatoes, sweet potatoes and pumpkin is rich in potassium, such as vegetables. Calcium rich food (Calcium rich foods play) Which is an important part of the heart and blood vessels as well as for muscle contraction generates the nerve impulse too.

Several other functions that it plays in the body include: balancing the electrolytes in our system, maintaining the acid-base balance and is significantly essential to muscle contraction and nerve transmissions throughout our body. A deficiency in sodium can put individuals at risk for contracting hyponatremia which is a dangerous condition in which an individual has too little sodium in their blood. The connection between sodium and water is directly correlated in keeping an equal ration of sodium and water in the body. For example, when the body contains too much salt, the body responds in keeping homeostasis by telling the individual to drink excessive water – polydipsia- until there is an equal balanced ratio of sodium to water. In addition, individuals who consume more than the recommended intake of salt tend to show signs of excessive weight gain, but in reality is just a side effect water weight in the body for this its way of maintaining a balance ratio until the salts are expelled from the body.

Your best option though would be chocolate milk because it has so much protein and repairs you sore achy muscles. Although most people drink water after sports Jason Karp said , “ It’s water but much much more!” This is important to know because if you think that chocolate milk is all sugar, you have to think again because it is really half water, half protein. Also chocolate milk is referred to professional athletes. Milk unleashed stated, “ Chocolate milk has been preferred more than sports drinks for Olympians and amateur athletes.”

Electrolyte Challenge: Sports VS Orange Juice Every year sport drink companies spend millions of dollars on advertising there drink they advertise what the drink can do and how it can help you stay awake during your day but what they advertise the most are the electrolytes they supply to your body. Electrolytes are minerals in your blood that you lose from sweat, they transfer energy through your body regulate fluid balance and transport nutrients they are very important to your health and help you overall with your day. In my project i am experimenting which gives you more of the needed electrolytes that help you stay awake. Sports drink A glance at the beverage aisle in a supermarket shows that sports drinks are growing in popularity

Moreover, for doing daily workouts, I tend to do on average 30-45 minutes. So with that being said, the water is more beneficial to me. This may be due, to the fact that the sports drink will just replenish back those calories burnt doing the workout session. I also know this because according to source a (infographic; sports drinks vs. water) its states that “Have water...for workouts under 60 minutes.”

Properties of Ionic and Covalent Substances Lab Report Introduction The purpose of this lab was to determine which of the following substances: wax, sugar, and salt, are an ionic compound and which are a covalent compound. In order to accurately digest the experiments results, research of definitions of each relating led to the following information: ionic compounds are positive and negatively charged ions that experience attraction to each other and pull together in a cluster of ionic bonds; they are the strongest compound, are separated in high temperatures, and can be separated by polar water molecules. A covalent compound forms when two or more nonmetal atoms share valence electrons; covalent compounds are also

Introduction: In this lab, of water in a hydrate, or a substance whose crystalline structure is bound to water molecules by weak bonds, is determined by heating up a small sample of it. By heating, the water of hydration, or bound water, is removed, leaving only what is called an anhydrous compound. Based on the percent water in the hydrate, it can be classified as one of three types: BaCl2O ⋅ 2H20, with a percent water of about 14.57%, CuSO4

Properties of Ionic and Covalent Substances Lab Report Introduction The purpose of this lab was to determine which of the following substances: wax, sugar, and salt, are an ionic compound and which are a covalent compound. In order to accurately digest the experiments results, definitions of each relating factor were researched, leading to the following information: ionic compounds are positive and negatively charged ions that experience attraction to each other and pull together in a cluster of ionic bonds; they are the strongest compound, are separated in high temperatures, and can be separated by polar water molecules. A covalent compound is formed when two or more nonmetal atoms share valence electrons; covalent compounds are also categorized into two sections: polar covalent and nonpolar covalent. Furthermore, polar covalent compounds dissolve in water, while nonpolar covalent compounds do not.

Water provides the Earth with the capacity of supporting life. Importance of water in humans In humans, water acts both as a solvent and a delivery mechanism, it dissolves essential vitamins and nutrients from food and delivers them to cells. Our bodies
