Sodium sulfate (Na2SO4) is a white crystalline compound used in detergents, paper, and glass manufacturing. Sodium thiosulfate (Na2S2O3) is a colorless crystalline compound used in Photography as a fixing agent and in medical treatments for cyanide poisoning. The key difference lies in their chemical structures and applications.
Sodium thiosulphate is typically white in color, appearing as a crystalline powder or solid.
To distinguish between these solutions: Copper sulphate solution will be blue in color. Sodium chloride solution will not exhibit any color and will form white crystals upon drying. Sodium nitrate solution will not exhibit any color and is typically used as an oxidizing agent. Sodium sulphate solution will not exhibit any color and may form white crystals upon drying.
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.
The boiling point of sodium thiosulfate is 100°C (212°F).
The chemical formula of sodium sulfate is Na2SO4.
Sodium thiosulfate is used in iodometry to titrate iodine, which allows for the determination of the concentration of substances that react with iodine. It serves as a reducing agent that reacts with iodine to form iodide ions in a redox reaction. This reaction is commonly used in analytical chemistry to quantify the amount of oxidizing agents present in a solution.
Sodium thiosulphate is typically white in color, appearing as a crystalline powder or solid.
Sodium thiosulphate (sulphate contains 4 oxygen atoms, thio-sulphate has one of these replaced by a sulphur atom). Dissolves away unexposed silver salts from photographic film or paper.
Sodium + Sulphate + Water = Sodium Sulphate + Water
because sodium thiosulphate is unstable and iodine also so to maintain neutral medium we have to use sodiumcarboate
