Sodium thiosulfate is an inorganic sodium salt composed of sodium and thiosulfate ions in a 2:1 ratio. It has a role as an antidote to cyanide poisoning, a nephroprotective agent and an antifungal drug.
Sodium hypochlorite decomposes both to chlorate and chloride, and to oxjygen and chloride. The relation between these reactions was by no means clear, and the oxygen evolution had been relatively little investigated. Hence ... small excess of sodium hydroxide to avoid hydrolysis to hypochlorous acid.
