In a titration, sulfuric acid of concentration \(0.1 moll^{-1}\) was added from a burette into a conical flask containing \(20cm^{3}\) of sodium hydroxide solution. The average titre was \(11.2cm ...

This requires a conical flask and gas syringe. Similarly, when calcium carbonate reacts with dilute hydrochloric acid, it produces carbon dioxide gas. We can measure the rate of the reaction by ...
