Alka seltzer in water a chemical change?

Answer 1

The purpose of this experiment was to determine how much time it would take for alca seltzer and water inside a film canister to react and make the lid of a film canister to pop off. There were four different controlled settings to determine the quantities, and the state of the alca seltzer to find out which of these four settings was the best way to create the most reaction in the same controlled environment (the film canister). Our class knows that alca seltzer and water combined creates a gas, so we decided to get into groups and figure out what is the best combination of alca seltzer and water to create this reaction in the fastest amount of time

When the Alka Seltzer is put into the water, in creates CO2 gas. Why is this?

The Alka-Seltzer have the main ingredient which is the baking powder. Baking powders have acetic acid or tartaric acid and sodium bicarbonate. When the tablet dissolves the components of baking powder(the acid and the base) react with one another and produces gas(CO2).

Answer 2

Alka seltzer contains both citric acid and sodium bicarbonate. When these molecules are put into solution together, they undergo an acid base reaction. This reaction produces sodium citrate and carbon dioxide as products, hence the fizzing of the solution.

Answer 3

Yes. Alka Seltzer in water is a chemical change. You are able to prove this by the formation of bubbles in the water when you drop the tablet in.

Answer 4

1 reason is because chemical and physical effects have taken change where molicules have been removed or changed and the effects are irreversable.

Answer 5

Because the alka- seltzer has a chemical called sodium bicarbonate that starts up the fizziness in the water
