What is the purpose of the gas collecting apparatus in the bicarbonate determination experiment?

to capture and measure the volume of gas

What is the function of the water in the gas collection apparatus?

water serves as a medium to collect and measure the volume of gas produced in the reaction and prevents gas from escaping

How can you measure the volume of gas collected in the gas collection apparatus during the reaction?

measured by noting the displacement of water in the graduated cylinder or buret
