Volumetric method for the estimation of tin(II) | SpringerLink

A rapid and easy volumetric method for the estimation of tin(II) has been proposed using copper sulphate solution. The method consists of liberating iodine from an excess of potassium iodide solution by the addition of a known volume of a standard copper sulphate solution and to this, adding a known volume of stannous chloride solution. The remaining iodine in the solution is titrated against ...

Potassium - Wikipedia

Potassium is a chemical element with the symbol K (from Neo-Latin kalium) and atomic number 19. Potassium is a silvery-white metal that is soft enough to be cut with a knife with little force. Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure. It was first isolated from potash, the ashes of plants, from which its name derives.
