Expert Solution

Net ionic equation - It is balanced chemical reaction equation in which all ionic compounds are written or expressed in the ionic state or aqueous state excluding spectator ions. Only aqueous species dissociate and rest which are present in solid, liquid or gas remains present in molecular state.

Spectator ions - They are the ions that are present on the right and the left side of the balanced chemical reaction. These ions do not participate in chemical reaction.

(a) The balanced molecular equation will be:

The complete ionic equation in separated aqueous solution will be,

$Sr^{2+}_{(aq)}+2OH^{-}_{(aq)}+2H^+_{(aq)}+2NO_3^-_{(aq)}\rightarrow Sr^{2+}_{(aq)}+2NO_3^-_{(aq)}+2H_2O_{(l)}$

In this above chemical equation, the species which are spectator ions are:

Hence, the net ionic equation is:

Or,

(b) The balanced molecular equation will be:

The complete ionic equation in separated aqueous solution will be,

$H^{+}_{(aq)}+ ClO_2^{-}_{(aq)}+Na^+_{(aq)}+OH^-_{(aq)}\rightarrow Na^{+}_{(aq)}+ ClO_2^{-}_{(aq)}+H_2O_{(l)}$

In this above chemical equation, the species which are spectator ions are:

Hence, the net ionic equation is:
