Question

Using a value of Ksp = 1.8 X 10-2 for the reaction PbCl2 Pb2+ + 2Cl -, the concentration of the products yields a value of 2.1 X 10-2:

Precipitation will occur.
Precipitation will not occur.

Answer 1

Precipitation will occur

Answer 2

Yes, Precipitation will occur.

Step-by-step explanation:

The solubility product of salt =
`K_(sp)=1.8* 10^(-2)`

Ionic product of the salt =
`K_i=2.1* 10^(-2)`

`K_i>K_(sp)` Precipitation

`K_i<K_(sp)` No Precipitation

Precipitation of salt occurs when its ionic product exceed sits solubility product.So, here in this case lead chloride's ionic product is greater than that of its solubility product which means that precipitation will occur. .
