Question

To determine the ph of different sample by using ph meter

Answer 1

Answer:

The pH of a solution may be accurately and easily determined by electrochemical measurements with a device known as a pH meter with a pH (proton)-sensitive electrode (usually glass) and a reference electrode (usually silver chloride or calomel). Ideally, the electrode potential, E, for the proton can be written as

Explanation:

where E is a measured potential, E0 is the standard electrode potential at aH+= 1 mol/L, R is the gas constant, T is the temperature in kelvin, F is the Faraday constant.

Answer 2

Explanation:

pH means power of hydrogen

To determine the ph of different sample by using ph meter

the colour of solution is identified

and then pH is decided
