Concentrated solutions are used to treat spillages of some chemicals. Sodium thiosulfate is safe to handle and store, but if it is mixed with an acid, a reaction happens. When dilute sodium thiosulfate is mixed with an acid, solid sulphur is made, which makes the solution appear cloudy.The reaction also makes small amounts of toxic sulphur dioxide gas.odium thiosulfate is safe to handle and store, but if it is mixed with an acid, a reaction happens.
