Explanation Weak diprotic acid: H 2 A Dissociation of weak acid in the solution is of very small extent. In water solution, the dissociation of weak acid is given below: H 2 A ( aq ) +H 2 O ( l ) ⇌ HA - ( aq ) +H 3 O + ( aq ) HA - ( aq ) +H 2 O ( l ) ⇌ A 2- ( aq ) +H 3 O + ( aq ) Due to the nature of weak diprotic acid of H 2 A , it dissociates in water solution with molecules. Other most of the species are found as molecular form of H 2 A . The acid dissociation constant value of second reaction is less than the first constant values because of that the ion formation of A 2- is negligible. Figure (a): In this figure, H 2 A molecules are shown.In that figure, A 2- ions and H 3 O + ions are present but there arezero HA − ions. To convert all HA − ions into A 2- ions is an impossible task. Equilibrium exists between HA − ions and A 2- ions. Without presence of HA − ions, existence of A 2- ions and H 3 O + ions is not possible

Question

Chapter 16, Problem 16.41CP

Interpretation Introduction

Interpretation:

The name of picture of weakest diprotic acid H2A 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.
