Does a precipitate form when you add 32.5 g of NaCl to 131.0 mL of 0.29 M Pb(NO3)2? (Ksp for possible ppt is 1.7 x 10-5)

What is Ksp?

The solubility product constant, Ksp​, is the equilibrium constant for a solid substance dissolving in an aqueous solution.

Writing the equation:

NaCl → [tex]Na^+[/tex]  + [tex]Cl^-[/tex]

[tex]Pb(NO_3)_2[/tex][tex]Pb^2^+[/tex]  + [tex]2NO^3^-[/tex]

[tex]Pb^2^+[/tex] + 2[tex]Cl^-[/tex] ↔ [tex]PbCl_2[/tex]

I.P = [ [tex]Pb^2^+[/tex]] * [ [tex]Cl^-[/tex] ]

Ksp [tex]PbCl_2[/tex] =[ [tex]Cl^-[/tex] ] * [[tex]Pb^2^+[/tex] ]

1.7 x [tex]10^-^5[/tex]= [ [tex]Cl^-[/tex] ] * [ [tex]Pb^2^+[/tex] ]

Molarity of NaCl = 4.24 M

Molarity of [tex]Pb(NO_3)_2[/tex] = 0.29 M

Ksp [tex]PbCl_2[/tex] =[ Cl- ] * [[tex]Pb^2^+[/tex] ]

Ksp << IP ⇒ precipitate formation will not take place.

Hence, the precipitate formation will not take place.
