Examination of Water | Industrial Pollution

In this article we will discuss about the physical, chemical and microbiological examination of water. Physical Examination of Water: (i) Colour: The colour is determined either by visual comparison of sample with known concentrations of coloured solution (by using Platinum Cobalt comparator) or by tintometric measurements. Platinum-Cobalt comparison method: Take 1.246 gm. of potassium chloroplatinate K2PtCl6 and 1 gm of [...]
