What is E in given equation?(a) induced emf(b) Faradays Constant(c) pH value deviation from 7(d) standard potentialThe question was posed to me by my school teacher while I was bunking the class.This is a very interesting question from Spirometry in section Pulmonary Function Analysers of Biomedical Instrumentation

Answer»

The correct answer is (a) induced emf

Explanation: The potential (E) of the GLASS electrode may be written by MEANS of the Nernst

equation:

where, Eo = standard potential R = gas constant T = absolute temperature F = Faraday constant DPH = pH value deviation from 7. The above relation shows that the emf developed in the electro-chemical pH CELL is a linear function of DpH.
