Chapter 3, Problem 127SAE

Interpretation Introduction

Interpretation:

The name of the compound that ends with −ate should be identified form the following options.

1. ${\text{HIO}}_{\text{4}}$
2. ${\text{Na}}_{\text{2}}{\text{SO}}_{\text{3}}$
3. ${\text{KClO}}_3$
4. $\text{HFO}$
5. ${\text{NO}}_2$

Concept introduction:

The compounds which are formed between two elements are known as binary compounds and if one element is metal and another is non-metal, then the binary compound are made up of ions known as binary ionic compounds.

First, the name of the metal should be identified with the help of its symbol.

The name of the non-metal should be identified with the help of its symbol and it is modified to end in “−ide”.

Polyatomic ions are those ions in which two or more atoms are joined with each other by covalent bonds. These ions are common, especially among non-metals.

Some non-metals form a sequence of oxoanions having different number of oxygen atoms. The name of these compounds are related with the oxidation state of non-metal atom to which oxygen atoms are bonded, ranging from hypo- (low) to per-(high) on the basis of number of oxygen atoms and oxidation state of non-metal.
