Applicants need to formulate and test a formula that gives the volume of the life preserver that would produce the minimum weight of sodium bicarbonate. Also, that when mixed with an excess of 1.0M HCl, it would inflate the life preserver to the pressure of 1300 torr using the following equation, NaHCO3 + HCl CO2 + H2O + NaCl. The objective of this experiment was to find out what was the least amount of sodium bicarbonate needed to react with an excess of 1.0 M HCl to inflate the bag. We were able to determine that around 22 grams of sodium bicarbonate were needed to firmly inflate the bag without bursting. Introduction The Acme Life Preserver Company needs to fill up a position within their company and they want to develop a new line of life preserves that inflate when the seal is broken with two mixing chemicals. Applicants must formulate and test a formula that gives the volume of the life preserver with the smallest amount of sodium bicarbonate that mixes with an excess of 1.0 M HCl and pressure of 1300 torr to inflate the life preserver. The balanced equation used to determine the volume of the life preserve
