stich3 [128]

Precipitation reaction is a chemical reaction used to separate the insoluble solid to the aqueous solution. This is a technique that is usually used to separate the impurities. By knowing the right chemical to react with, only the pure acid will react and dissolve with ether. The impurity will be precipitated and will settle to the bottom.

olya-2409 [2.1K]

Answer : The correct option is, (b) $2Na^+$

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,

$Na_2S(aq)+MgCl_2(aq)\rightarrow 2NaCl(aq)+MgS(s)$
