From the balanced molecular equation, write the complete onic and net ionic equation for the following:
(a)k2c2o4 + ba(oh)2 - > 2koh + bac2o2
(b)pb(no3)2 + h2so4 -> 2hno3 + pbso4
(c)caco3 + h2so4 = co2 + caso4 + h2o

Answer : The net ionic equation will be,

(a)

(b)

(c)

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.

(a) The given balanced ionic equation will be,

The ionic equation in separated aqueous solution will be,

In this equation, 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,

(b) The given balanced ionic equation will be,

The ionic equation in separated aqueous solution will be,

In this equation, 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,

(c) The given balanced ionic equation will be,

The ionic equation in separated aqueous solution will be,

In this equation, is 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,
