Chemical Reaction Of Alka-Seltzer In Water

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.

Stretch the open end of the balloon around the mouth of the bottle and hold it there. 6. Observe the reaction and record how fast the Alka-Seltzer dissolves. 7. Place an Alka-Seltzer tablet into a second empty water bottle.

They also helped me by testing it at home.

Baking soda and citric acid mixed when dropped in the water, which causes a chemical reaction to happen. There are multiple components that make an alka-seltzer dissolve.

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.

Develop a Hypothesis If seven mentos to a 2L bottle of Diet Pepsi, then it will create the biggest geyser out of Coke, Fanta, & Root Beer because Diet Pepsi has potassium benzoate, aspartame, and the carbonation which react to mentos. Design an Experiment Materials List: 1 clear test tube 35 original flavored Mentos candies (2 1/2 rolls) 1 3x5 index card 4 2L bottles of soda (all different flavors/types) 1 2L bottle of soda water 1 100 mL graduated cylinder 1 400 mL beaker 1 pair of tweezers (preferably large) 1 small container Procedure: Stack seven mentos in the test tube When given permission take the test tube, soda bottles, index cards, and the remaining 25 mentos, to the designated area Place one of the four soda bottles on a flat area Open the soda bottle and place the 3x5 index card over it With the index card over the soda bottle, flip the test tube over and place it on the index card, so the test tube is lined with

If I had a household product labeled sodium bicarbonate, I would add an acidic substance and expect bubble to be created. As we know acid reacts with bubbles when combined with sodium bicarbonate. 2.

When the gummy bear was placed in distilled water, the water entered the gummy bear making it increase in size because the concentration inside the gummy bear was greater than the outside of the gummy bear. When the gummy bear was placed in tap water, the gummy bear expanded due to osmosis. The gummy bear is made of glucose, salt, etc and the water in the cup surrounding it moved into the bear because water moves from high concentration (cup of water) to low concentration (gummy bear). As a result the bear collected a significant amount of water causing it to become much larger in size.

Alka-Seltzer tablets are used to treat headaches, stomach and body aches and also heartburn. They consist of citric acid (C6H8O7), baking soda (NaHCO3), and aspirin (C9H8O4). The fizzing observed is a result of a chemical reaction between the citric acid and baking soda which form carbon dioxide in turn causing the fizzing. When the tablets are dropped into water they dissolve and dissociate into the ions in the equation: C6H8O7 (s) → 3H+ (aq) + C6H5O7 3- (aq).

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

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

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.

The other time where mass could have been lost was during reaction 3, more specifically each time the liquid was decanted. Although a few black sand-coffee grains of the copper (II) oxide lost do not seem like a significant amount, they do have an impact on the final result, and each time a few of the grains were accidentally decanted could have an impact on why our final recovered mass was less than the initial amount that we began

This reaction is an acid base reaction thus results expected to show some carbon dioxide. Method: A 20ml vinegar is poured in the 250ml bottle. A funnel is used to pour 3g of baking powder in the balloon by sticking the funnel in the neck of the balloon to easily allow the baking powder inside without it spilling on the sides. Slowly but surely the balloon is placed on the mouth of the bottle by stretching it gentle so that it does not tear. A 10cm string is used to tie the balloon on mouth of bottle so that air may not intrude and no air formed be lost.

Acids are proton donors in chemical reactions which increase the number of hydrogen ions in a solution while bases are proton acceptors in reactions which reduce the number of hydrogen ions in a solution. Therefore, an acidic solution has more hydrogen ions than a basic solution; and basic solution has more hydroxide ions than an acidic solution. Acid substances taste sour. They have a pH lower than 7 and turns blue litmus paper into red. Meanwhile, bases are slippery and taste bitter.
