The discussion revolves around the balancing of the chemical equation HCl + Na2S2O2 --> NaCl + S + H2O + SO2. It is noted that there is a mistake in the formula for sodium thiosulphate, which should be Na2S2O3, affecting the ability to balance the equation correctly. Additionally, participants discuss methods for measuring the rate of reaction, specifically mentioning the mass measurement technique where the mass of reactants is weighed until a change occurs. A request for diagrams related to the experiment is made, with an emphasis on sharing helpful websites for reference.
