Question

write commercial use of agcl

Answer 1

Here is your answer..... Mate...

Commercial reference electrodes consist of a plastic tube electrode body. The electrode is a silver wire that is coated with a thin layer of silver chloride, either by electroplating or by dipping the wire in molten silver chloride. 

A porous plug on one end allows contact between the field environment with the silver chloride electrolyte. An insulated lead wire connects the silver rod with measuring instruments. A voltmeter negative lead is connected to the test wire. The reference electrode contains potassium chloride to stabilize the silver chloride concentration. 

The potential of a silver:silver chloride reference electrode with respect to the standard hydrogen electrode depends on the electrode composition.....
