Question: Calculate the solubility (g/L) of CuBr at 25 degrees celsius in 0.0110 M CoBr2. Ksp of CuBr = 5.3*10^-9. I am capable of doing it in pure water, but I am struggling with how the two bromines in CoBr2 will affect the answer and ICE TABLE set up....

Follow up work: CuBr --> Cu + Br CoBr2 --> Co + 2 Br Set up for solubility in pure water: 5.3*10^-9 = x^2 x= 1.5 g/L Set up (?) for solubility in 0.011 M CoBr2: 5.3*10^-9 = (x)(0.022+x)

Sorry: for solubility in water x multiplied by the molar mass equals 1.5 g/L

Thank so much Dr. Bob!!
