Question

Assuming that the solubility of PbBr2 is 2.1x10^-2 calculate the ksp for this salt

Answer 1

What unit? g/L or mol/L

Answer 2

mol/L

Answer 3

Tip: Write down the dissolution equation first.

Answer 4

PbBr_2_ --> Pb^2+^+2Br^-^??

Answer 5

Correct
\(PbCl_2 \rightarrow Pb^{2+}+2Cl^-\)

Now what are the concentrations of \(Pb^{2+}\) and \(Cl^-\) in the saturated solution?

Answer 6

x & 2x?

Answer 7

or x & 2x^2^?
