What is the reaction between sodium thiosulphate and FeCl3?

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.


What is the balance reaction equation of bromine and sodium thiosulfate?

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.


What is the reaction of sodium sulphite and sulphur?

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.


What is the type of chemical reaction between Sodium Thiosulphate reacts and hydrochloric acid and what is the balanced equation?

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.


Is the dissolving of sodium thiosulfate in water endothermic or exothermic reaction?

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.


Reaction of bromine with sodium thiosulfate?

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.


What is the product of sodium thiosulfate and hydrochloric acid?

Produces Sodium iodide, Water, Sulfur and Sulfur dioxide


What is the reaction between sodium hypochlorite and copper?

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.


What happens when sodium peroxide comes in contact with sodium thiosulfate?

An exothermic reaction will occur, with the peroxide being reduced and the thiosulfate being oxidized.


What is the reaction between sodium thiosulphate and iodine?

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.


Why amnomiun thiocyanate is added in the titration of sodium thiosulphate with copper?

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.


What is the product of sodium hydroxide plus copper sulphate?

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.
