Chapter 16, Problem 16.41CP

Interpretation Introduction

Interpretation:

The name of picture of weakest diprotic acid ${\text{H}}_{\text{2}}\text{A}$ and impossible solution needs to be determined.

Concept introduction:

A chemical species that accepts electrons and donates protons or hydrogen ions is known as acid. In most acids, hydrogen atoms bonded that release to yield anion and cation in water.

The strength of the acid depends on the size and electronegativity of the atom directly attached to H atom.
