Webb28 mars 2024 · It is also possible to prepare iodine solutions by mixing potassium iodide with potassium iodate in the presence of strong acid: 5I− + IO3− + 6H+ → 3I2 + 3H2O. Potassium iodate is a primary substance, so the solution prepared in this way can have exactly a known concentration. However, this approach is not cost-effective and in lab ... WebbThe thiosulphate reaction is a chemical reaction that involves the use of a thiosulphate compound, such as sodium thiosulphate or potassium thiosulphate. Thiosulphates are compounds that contain sulfur and oxygen atoms bonded to a central sulfur atom, with the general formula S2O3^2-.
