You have amisture that is 0.100mol/L in each of the following ions: Cl-, Br-, and I-. (a) Which substance will precipitate first? AgCl, AgBr, AgI? (b)what is the concentration of Ag+ required to start the precipitation of the first substance? ksp (AgCl)=...

Given a saturated solution of CaF2, write the ionic equilibrium and use it to calculate the solubility of CaF2. My answer for the ionic equation is CaF2(s)<->Ca2+(aq)+ 2F-(aq) Ksp= [Ca2+][F-]2 the given ksp is 3.32*10-4 how do i figure out the solubility?...

what Is the square root of 13

ksp=(x)(2x)2=3.32*10^-4 = (x)(4x2)=3.32*10^-4 = 4x3=3.32*10^-4 then i took the cubed root of that and got 2.02*10^-4??? is that correct?

i got 4.46*10^-4??

for this same question it also asks... what will happen to the value of ksp? and Calculate the new solubility of CaF2 (in 0.100mol/L NaF) how do i go about doing the second part? the ksp will increase beacuse you are adding more to the solution?

I think it’s 36 because 5 times 12 is 60 and 3 times 12 is 36.
