Chapter 14, Problem 14.60P

Interpretation Introduction

Interpretation:

The increasing order of acidity aqueous solutions of ${\text{Sb}}_{\text{2}}{\text{O}}_{\text{3}}{\text{, Bi}}_{\text{2}}{\text{O}}_{\text{3}}{\text{, P}}_{\text{4}}{\text{O}}_{\text{10}}{\text{ and Sb}}_{\text{2}}{\text{O}}_{\text{5}}$ has to be given.

Concept Introduction:

Increasing acid strength:

The hydrohalic acids are strong acids ($\text{HCl, HBr, and HI}$) other than ($\text{HF}$).

Oxoacids are strong acid when the number of oxygen excess than the ionizable proton by two or more oxygen atom for example, ${\text{HNO}}_{\text{3}}{\text{, H}}_{\text{2}}{\text{SO}}_{\text{4}}{\text{, and HClO}}_{\text{4}}$.

The hydrogen atom which is not bonded to halogen atom or oxygen atoms are weak acid for example ${\text{HCN, H}}_{\text{2}}\text{S}\text{.}$

The number of protons is equal to number oxygen in Oxoacids are weak acid for example ${\text{ HClO, HNO}}_{\text{2}}{\text{, and H}}_{\text{3}}{\text{PO}}_{\text{4}}$. In general, carboxylic acids are weak acid ($\text{RCOOH}$).

Order of acidity in periodic table:

Across the left to right acidity is an increase due to increasing electronegativity and up to down acidity is decrease due to increasing atomic size.
