- Homework Statement:
- Calculate the concentration of the first cation until second cation just starts to precipitate as sulfate
- Relevant Equations:
I got the first question correct but I don’t understand the answer given for second question which is c (Pb^2+) = 8.4x10^-5 molL ^-1. It divided the concentrate for sulphate ion of Ag2SO4 into 2 , but it is the solubility right ?
