Research Question: To investigate and compare how different temperature (5℃, 15℃, 25℃, 35℃, 45℃) can affect the concentration of carbon dioxide in soda water through titration with sodium hydroxide solution. Introduction: Carbon dioxide plays an important role in soft drinks. Soda water is manufactured by pumping carbon dioxide into water under high pressure. Carbon dioxide dissolves in water to form carbonic acid, which is the fizz we find in soft drinks. CO2 + H2O ⇌ H2CO3 The popping sound we hear when we open the can of fizzy drink, the bubbles and sparkle we see in the soft drink, and the feeling of bubble popping on your tongue, all of these are due to carbon dioxide escaping from solution. One of the reasons people love to drink …show more content…
The soda water will be stored in 5 different temperatures : 5℃, 15℃, 25℃, 35℃, and 45. The desired temperatures will be achieved by using the water bath and refrigerator. I chose phenolphthalein as the indicator, because it is commonly used for titration and is a weak acid. Phenolphthalein is usually used when the solution is strong base and weak acid. When it is added into an acidic solution, the solution will be colourless; when it is added into an alkaline solution, the solution will turn pink. Standard Sodium hydroxide solution is the alkaline solution that will be used to titrate with soda water as it is a common solution that can be easily found in an ordinary school laboratory. It is a strong base. Carbonic acid is a weak acid which will react with a strong base to form a basic (pH > 7) solution. When Phenolphthalein is added to Soda water, the resultant solution is colourless. After titration with a strong base (sodium hydroxide), the solution will turn to pink as the solution becomes
The temperature probe was kept in the calorimeter until the temperature had been stabilized and was calibrated. A beaker was placed on a hot plate with dial turned between three and four. Another 100.00 ml of deionized water was added while the beaker is heating up. Using the temperature probe, the beaker was measured
Alka-Seltzer is a medical drug that works as a pain reliever and an antacid. The pain reliever used is aspirin and the antacid used is baking soda. When sodium bicarbonate dissolves in water it splits apart into sodium and bicarbonate ions. The bicarbonates reacts with hydrogen ions from citric acid to form carbon dioxide gas and water. This is how the bubbles are made.
Hypothesis If I put pop rocks in different sodas reacts differently to the soda, then I think certain sodas have more carbonation or sugar. Research Pop Rocks are made of sugar, carbon dioxide, water, and flavoring. They Coca cola 's ingredients are
Introduction Alka-Seltzer has been on the market since 1931 and has helped to relieve indigestion and upset stomach. The tablets began to fizz and bubble when dropped into water. “The fizziness happens when baking soda (sodium bicarbonate) and citric acid react chemically in water. They yield sodium citrate, water and carbon dioxide gas, which causes bubbles.” Based on this information, we will measure the reaction time of AlKa- Seltzer dissolved in 200 ml of water at 3 different tempertures in the first portion of this experiment.
My hypothesis was correct because Diet Pepsi has the least amount of soda left in the bottle of the explosion out of Coke, Root Beer, Fanta, and Soda water. According to the data table Diet Pepsi had the smallest amount of soda left in the bottle, it had 620 mL left. I think my hypothesis was correct because like stated in the hypothesis, Diet Pepsi contains potassium benzoate, aspartame, and the carbonation which react to mentos. Specifically, the tiny pores in the mentos which helps the geyser form. Though, the other sodas tested contained carbonation, potassium benzoate and aspartame, have a role in the reaction to the
Sodium Bicarbonate mixed with Hydrochloric acid. The chemical reaction observed showed that there was fizzing and bubbling, this is evidence that a new gas was being produced. This new gas, CO2 was generated from the reaction. After the fizzing stopped a liquid was leftover leading me to conclude the liquid leftover leading me to conclude the liquid leftover was the NaCl and H2O 4. You found a sample of a solution that has a faint odor resembling vinegar (an acid).
The higher the temperature, the faster it takes for the citric acid and baking soda to react. When the temperature is lower, it will take less time for the chemicals to
Soda Carbon Dioxide and Propulsion Relation Experiment For this assessment we had to solve and answer problem by designing a fair and accurate experiment. Sodas and carbonated drinks are one of the many things we see in our life. Our group has looked into carbonated drinks and how they work.
In each of the experimentations I studied, I have determined how the temperature of the water alters the speed of the Alka-Seltzer tablets being disintegrated. I have selected to differentiate on these two specific components because I wanted to collate and evaluate the number of carbon dioxide being created from the two dissimilar water temperatures. 3. The other key essentials I needed in order to control my experimentations were how much time it took, the quantity of water being utilized, and the temperature of the water. I have controlled both of these key essentials by utilizing a timer, a graduated cylinder, and a thermometer.
Soda can hurt you in many different ways. As it states in the 2 articles about sugary drinks. The 2 author names are Russ Floyd and Evan Cook. Russ Floyd kinda has a point in his article since they do affect you. But Evan Cook has a point to since it is your body.
Weighed 1 gram of NaC2H3O2 and mixed it with ionized water. Boiled 12 mL of 1.0M Acetic Acid added into a beaker containing the sodium carbonate on a hot plate until all the liquid is evaporated
Pop Rocks and soda have a very interesting chemical reaction with each other. Soda is a very pressurized drink that has carbon dioxide in it. Carbon dioxide is a pressurized chemical. When it is shaken, it fizzes, and causes pressure, and overflows releasing the carbon dioxide. It is similar to the Pop Rocks.

Have you ever just wanted to have a soda at school? Have you ever been having a bad day at school and just want a nice cool, refreshing beverage, but then you realize… you’re at school? According to NY daily news “soda gets a bad rap for making us fat, rotting our teeth and even possibly making us depressed. But hey... it's not all bad news with the bubbly stuff.” A weird fact about soda is “soda is one of society’s favorite beverages.
The equation of the reaction between sodium hydroxide and ethanoic acid is as follows: CH3COOH + NaOH → CH3COONa + H2O We can measure the end point of titration process and we can also measure the amount of reactants. The concentration of ethanoic acid in the vinegar can be determined through stoichiometric calculations, Using the values obtained from the titration, and also the chemical equation as a reference. Phenolphthalein indicator is used in this acid-base titration Equipment and materials:
