8-23 Write the formula for the conjugate acid of each base.

(a) H2O

(b) HPO42-

(c) CH3NH2

(d) PO43-

Expert Solution
Interpretation Introduction

(a)

Interpretation:

The formula for conjugate acid of given chemical substance to be identified.

Concept Introduction:

A base accepts proton in aqueous solution to produce conjugate acid along with conjugate base. In turn the conjugate acid releases proton again to produce base.
