Write a procedure that you would follow to demonstrate the effect of increasingly higher concentrations of hydrochloric acid on its rate of reaction with antacid tablets.

The reaction would produce bubbles of gas.

We can prepare 3-5 test tubes of acid with increasing concentrations. Then, we add antacid tablets to each and note the time taken for the tablet to dissolve and stop producing bubbles. The lesser the time taken, the greater the rate of reaction.

Well to my expert knowledge and my exquisite calculations i think the the negative ion # 412 is the key to sucess

Deposition is the transition of matter going from gas to solid without passing through the liquid phase.a.) gas—-> solid
