Question

Determine the net iconic equation for the following chemical reaction: HCl(aq) + NH4OH(aq)———-> NH4Cl(aq) + H2O(I) Hint: HCl(aq) is strong acid NH4OH(aq) is a weak base

Answer 1

Answer : The net ionic equation will be,

`H^(+)(aq)+OH^(-)(aq)\rightarrow H_2O(l)`

Explanation :

In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

The given balanced ionic equation will be,

`HCl(aq)+NH_4OH(aq)\rightarrow NH_4Cl(aq)+H_2O(l)`

The ionic equation in separated aqueous solution will be,

`H^+(aq)+Cl^-(aq)+NH_4^+(aq)+OH^-(aq)\rightarrow H_2O(l)+NH_4^+(aq)+Cl^-(aq)`

In this equation,
`NH_4^+\text{ and }Cl^-` are the spectator ions.

By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.

The net ionic equation will be,

`H^(+)(aq)+OH^(-)(aq)\rightarrow H_2O(l)`
