1. The problem statement, all variables and given/known data Hello all, This is a problem on a worksheet I was given and Im stumped! Statement: Will a ppt form when 35.00 mL of 1.0x10^-3 M CoSO4 is mixed with 15.00 mL of 7.50x10^-4 M Al2(SO4)3 and 200 ml of a buffer which is .200 M NH3 and .200 M NH4Cl? I do not need the answer, I just need a nudge in the right direction. 2. Relevant equations Ksp Al(OH)3 = 5x10^-33 Ksp Co(OH)2 = 3x10-16 3. The attempt at a solution I'm not even sure where to start. I would usually write out the net ionic eqn in this situation then use an ICE table but I'm not sure even what the ionic equation will look like here. We didnt go over molar solubility that much in my lecture, so all the problems were relatively straight forward till I got to this one. There just seems to be a lot going on. Any help? Thanks in advance.
