Chapter 8.2, Problem 24PP

Interpretation Introduction

Interpretation:

The name of periodic acid needs to be determined.

Concept introduction:

In periodic acid of iodine, it is present in highest oxidation state that is +7. It is present in two forms one is orthoperiodic acid and metaperiodic acid.

Answer to Problem 24PP

${\text{HIO}}_4$

Explanation of Solution

${\text{HIO}}_4$ is called the periodic acid, as it has the highest oxidation $\left(+7\right)$ are known as highest oxoacid of iodine.

It can be present in two form

1. Orthoperiodic acid ${\text{H}}_3{\text{IO}}_6$

2. Metaperiodic acid ${\text{HIO}}_4$

But metaperiodic acid is periodic acid.

Its molecular weight is $191\cdot 9\text{ g/mol}$ and melting point is $128\cdot 5°6$. Chemical name is prraperiodic acid and hydrogen periodate.

Periodic acid is soluble in water as well as alcohols.

Conclusion

Periodic acid is the highest oxoacid of iodine with the $+7$ oxidation state.
