通过理论计算与实验证明,确定次氯酸钙溶液与二氧化碳反应的产物为碳酸钙而非碳酸氢钙,并指出正确确定溶液pH是本实验的关键。
Through theoretical calculations and experiments, it is confirmed that the product of the reaction between calcium hypochlorite and carbon dioxide is calcium carbonate instead of calcium bicarbonate, and the correct determination of the pH of the solution is the key point in this experiment.
