What happens when sodium thiosulfate reacts with water?
An exothermic reaction gives off heat, like our hot pak. The sodium thiosulfate needs energy to dissolve, so it takes heat from its surroundings, in this case the warm water. The heat is absorbed into the sodium thiosulfate and the water is now cold.
Why sodium thiosulphate is added to water?
Sodium thiosulfate is a satisfactory dechlorination agent that neutralizes any residual halogen and prevents bactericidal action from continuing during transit. For a 120 ml bottle, 0.1 ml of a 10%solution of Na2S2O3 will neutralise a sample containing up to 15 mg/l residual chlorine.
Does Na2S2O3 dissolve in water?

|---|---|
| Description | 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. It contains a thiosulfate(2-). ChEBI |
What is the hypo solution?
Hypo Solution is the abbreviation for sodium thiosulphate or sodium hyposulphite. It is used for both film and photographic paper processing, the sodium thiosulfate is known as a photographic fixer and is often referred to as ‘hypo’, from the original chemical name, hyposulphite of soda.
What is the order of reaction for sodium thiosulphate and hydrochloric acid?
Na2S2O3(aq) + 2HCl(aq) S(s) + SO2(g) + H2O(l) + 2NaCl(aq) Has a rate equation of the type: reaction rate = k [Na2S2O3]1[HCl]1 = k [Na2S2O3] [HCl] The reaction is first order with respect to Na2S2O3 and is first order with respect to HCl. …read more.
