What are the concentrations of each of the ions in a saturated solution of PbBr2, given the Ksp of PbBr2 is 2.1 x 10^-6?
I get stuck in solving this question when I get to the equation4(x^3)=2.1 x 10^-6 and I don't know how to get to the answerx = 8.07 x 10 ^-3 M which is susposedly the concentration of Pb 2+.
