Chapter 8.2, Problem 20PP

Interpretation Introduction

Interpretation:

The acid ${\text{HClO}}_{\text{3}}$ should be named.

Concept introduction:

Name of acid is related to name of parent anion. Acid formed from anions whose names end in −ide have prefix hydro and ending −ic.

Answer to Problem 20PP

Name of the compound ${\text{HClO}}_{\text{3}}$ is chloric acid.

Explanation of Solution

Given acid is ${\text{HClO}}_{\text{3}}$. In the compound anion is ${\text{ClO}}_{\text{3}}{}^{-}$ (chlorate). Name the acid by removing −ate and adding −ic. Then add ‘acid’ word. Thus name of the compound is chloric acid.

Conclusion

If oxyanion in acid ends in −ate, change the ending with −ic, than add ‘acid’ word.
