Which of the following is a product when a solution of MgCl2(aq) is mixed with a solution of Pb(NO3)2(aq)?

a. PbCl2(aq)
b. PbCl2(s)
c. Pb(NO3)2(s)
d. MgCl2(s)
e. Mg(NO3)2(s)

The product formed in the solution is

Explanation:

Double displacement reaction is defined as the reaction in which exchange of ions takes place.

The chemical equation for the reaction of magnesium chloride and lead nitrate follows:

By Stoichiometry of the reaction:

1 mole of aqueous magnesium chloride reacts with 1 mole of aqueous lead nitrate to produce 1 mole of solid lead chloride and 1 mole of aqueous magnesium nitrate

Hence, the product formed in the solution is

they are all solids.
