Question

in determination of pH by
measuring EMF of cell....,,electrode
is used as reference electrode,​

Answer 1

Answer:

Aqueous reference electrodes Common reference electrodes and potential with respect to the standard hydrogen electrode: Standard hydrogen electrode (SHE) (E=0.000 V) activity of H+=1 Molar. Normal hydrogen electrode (NHE) (E ≈ 0.000 V) concentration H+=1 Molar. Reversible hydrogen electrode (RHE) (E=0.000 V - 0.0591*pH ...
