An aqueous solution of sodium sulfate is allowed to react with an aqueous solution of calciumnitrate. the complete ionic equation contains which of the following species (when balanced in stan-dard form)? a.2na+aq)b.2so42-(aq)c.3ca2+(aq)d. no3-(aq)e. k+(aq)

Answer : The correct option is, (a)

Explanation :

Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and present in an aqueous are represented in the form of ions.

Net ionic equation : 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 balanced molecular equation will be,

The complete ionic equation in separated aqueous solution will be,

In this equation the species present are, are the spectator ions.

Hence, the complete ionic equation contains specie is

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.
