Question

What is the value of the ionic product of water at 298k?

(a) 7 x 10^-14/mol^2L^2

(b) 1 x 10^-10/mol^2L^2

(c) 1 x 10^-14/molL^2

(d) 1 x 10^-14/mol^2L^2

I had been asked this question in an interview for internship.

This interesting question is from Equilibrium topic in portion Equilibrium of Chemistry – Class 11

Answer 1

Right option is (d) 1 x 10^-14/mol^2L^2

Explanation: Ionic product is a product of the concentration of hydronium ions and hydroxyl ions in pure water, which remains constant at a particular temperature. It is symbolized as KW and is equal to  1 x 10^-14/mol^2L^2.
