In standard methods it says to dissolve 3.5 g sodium thiosulfate in water and dilute to 1 L. Use 1 ml reagent to remove 1 mg/L residual chlorine in 500 ml sample.
A solution of sodium thiosulfate is produced.
Produces Sodium iodide, Water, Sulfur and Sulfur dioxide
To prepare 0.02M sodium thiosulfate solution, weigh out the required amount of sodium thiosulfate pentahydrate (Na2S2O3·5H2O) or anhydrous sodium thiosulfate (Na2S2O3). Dissolve this in distilled water and make up the volume to the desired concentration. Make sure to use a volumetric flask for accuracy and precision in preparing the solution.
S2O32-(aq) + 2H+(aq) ---> S(s) + SO2(g) + H2O(l)
Yes, sodium thiosulfate is soluble in water. It dissolves readily in water to form a clear solution.

Sodium Thiosulphate is Na2S2O3 and water is H2O.
Produces Sodium iodide, Water, Sulfur and Sulfur dioxide
When water is mixed with sodium thiosulfate the surrounding area temperature decreases causing the temperature to become, colder. for example; the water is at 22.5 C when you mix it with sodium thiosulfate the temperature could decrease up to 19.5 C this is because sodium thiosulfate an endothermic reaction which makes new bonds with the water and the sodium thiosulfate
The dissolving of sodium thiosulfate in water is an exothermic reaction. This means that heat is released during the process as the sodium thiosulfate molecules form bonds with water molecules.

Yes, sodium thiosulfate is soluble in water. It dissolves readily in water to form a clear solution.
To prepare a 0.05 Normal solution of sodium thiosulfate, you would dissolve the appropriate weight of sodium thiosulfate pentahydrate in a known volume of water to achieve a concentration that corresponds to 0.05 N. The molar mass of sodium thiosulfate pentahydrate (Na2S2O3·5H2O) is 248.18 g/mol. You can calculate the weight needed using the formula: (Normality) x (Equivalent weight) x Volume = Weight of the compound.
Adding sodium thiosulfate crystals to water causes an endothermic reaction, meaning it absorbs heat from the surrounding environment. As a result, the water temperature decreases, making it go cold.
When sodium thiosulfate dissolves in water, it undergoes a physical change rather than a chemical reaction. The sodium thiosulfate molecules are surrounded by water molecules, causing them to separate and disperse throughout the solution. This process is known as dissolution, where the ionic compound breaks apart into its constituent ions without any chemical bonds being broken or formed.
