Question

How many ions are present in (NH4)2CO3 ? ...?

Answer 1

3 ions are present in
`(NH_4)_2CO_3`.

Step-by-step explanation:

Ammonium carbonate is made up two ammonium ions and 1 carbonate ions.

1. Ammonium ion with valency of +1.

2. Carbonate ions with valency of -2.

By Criss-cross method we get:

`(NH_3)_2(CO_3)_1`

When 1 mole of ammonium carbonate is dissolved in water it gives 2 moles of ammonium ions and 1 mole of carbonate ions.The chemical equation is given as:

`(NH_4)_2CO_3(aq)\rightarrow 2NH_4^+(aq)+CO_(3)^(2+)(aq)`
