Question

Ion selective electrodes have ________ linear range and _________ detection limit than the pH electrode.

(a) Lower, lower

(b) Lower, higher

(c) Higher, lower

(d) Higher, higher

This question was addressed to me in quiz.

I would like to ask this question from Ion Selective Electrodes-Principle and Types topic in chapter pH Meters and Ion Analysers of Analytical Instrumentation

Answer 1

The correct option is (b) Lower, higher

The explanation is: Ion selective electrodes have a lower linear range and higher detection limit than the pH electrode. It works on effectively narrow pH.
