During this process, the mixture should be boiled in order to remove the CO2 formed. When the CaCO3 addition is complete, it is observed that a sufficient amount of precipitate is formed at the bottom of the container. The solution is filtered while hot, the excess water is evaporated and cooled with ice water. Thereupon, he says 25-30 mL of 6% H2O2 solution, 5 mL.
