With an Ag concentration of 0.020 M and a Pb2+ concentration of 0.0010 M, Only PbSO₄(s) will precipitate. The correct option is C.

What is molarity?

Molarity is the measure of the concentration of any solute in per unit volume of the solution.

The equations are

[tex]\rm Ag_2SO_4--- > 2Ag++SO4^{-2}[/tex]

[tex]PbSO_4--- > Pb_2+ +SO4^{-2}[/tex]

Therefore:

[tex]Ag_2SO_4=[0.02^2[0.001]]\\Ag_2SO_4=4 \times 10^{-7}[/tex]

and

[tex]PbSO_4=[0.001^2[0.001]]\\PbSO_4=4*10^{-6}[/tex]

Since, [tex]PbSO_4 > > PAg_2SO_4[/tex], only  PbSO₄ will precipitate.

Thus, the correct option is (C) Only PbSO₄(s) will precipitate.
