The reaction between sodium thiosulfate and copper is as follows:
2Na2S2O3 + Cu → CuS + Na2S4O6
The reaction between sodium thiosulfate (Na2S2O3) and FeCl3 forms a complex of iron (III) thiosulfate, Fe(S2O3)3. This complex has a yellow color due to the presence of iron (III) ions. The reaction is often used in analytical chemistry for the titration of thiosulfate ions.
The balanced chemical equation for the reaction between bromine and sodium thiosulfate is: 2Na2S2O3 + Br2 → 2NaBr + Na2S4O6. This reaction is often used in titrations to determine the concentration of bromine in a solution.
When sodium sulfite reacts with sulfur, it forms sodium thiosulfate. This reaction typically involves the oxidation of sodium sulfite by sulfur to produce sodium thiosulfate.
The reaction between sodium thiosulfate and hydrochloric acid is a redox reaction, where the sulfur in thiosulfate changes oxidation state. The balanced equation for this reaction is: 2Na2S2O3 + 2HCl -> 2NaCl + SO2 + S + H2O.

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.
When bromine reacts with sodium thiosulfate, it undergoes a redox reaction where bromine is reduced to bromide ions and thiosulfate is oxidized to form sulfate ions. The reaction can be used to titrate bromine in solution, as thiosulfate acts as a reducing agent, consuming the bromine until all the thiosulfate is oxidized.

The reaction between sodium hypochlorite and copper results in the formation of copper(II) oxide and sodium chloride. This is an oxidation-reduction reaction where the sodium hypochlorite oxidizes the copper metal to form copper oxide and is itself reduced to sodium chloride.
An exothermic reaction will occur, with the peroxide being reduced and the thiosulfate being oxidized.
Sodium thiosulfate reacts with iodine to form sodium iodide, sodium tetrathionate, and sulfur dioxide. This reaction is often used in titrations to determine the concentration of iodine in a solution.
Ammonium thiocyanate is added in the titration of sodium thiosulphate with copper to detect the end point of the reaction. When all the thiosulfate ions react with copper ions, excess copper ions will react with ammonium thiocyanate forming a reddish-brown complex. This color change indicates that all the thiosulfate has reacted and the titration is complete.
The reaction between sodium hydroxide and copper sulfate will result in the formation of sodium sulfate and copper hydroxide. The products of this reaction will be a blue precipitate of copper hydroxide and a solution of sodium sulfate.
