Answer 1

Answer : The net ionic equation will be,

`Ba^(2+)(aq)+SO_4^(2-)(aq)\rightarrow BaSO_4(s)`

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,

`Ba(OH)_2(aq)+H_2SO_4(aq)\rightarrow 2H_2O(aq)+BaSO_4(s)`

The ionic equation in separated aqueous solution will be,

`Ba^(2+)(aq)+2OH^-(aq)+2H^(+)(aq)+SO_4^(2-)(aq)\rightarrow BaSO_4(s)+2H^+(aq)+2OH^(-)(aq)`

In this equation,
`H^+\text{ and }OH^-` 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,

`Ba^(2+)(aq)+SO_4^(2-)(aq)\rightarrow BaSO_4(s)`
