For a saturated solution of CaF2 buffered at pH 3.0,
answer the following questions.
( Ksp = 3.2*10^(-11) for CaF2; Ka = 6.8*10^(-4) for HF )
(a) Write the pertinent equilibrium constant expressions for the solution.
(b) Write the mass balance equation.
(c) Find the solubility of CaF2 in the solution.
我自己想了很久，還是解不出來，請各位高手幫幫忙<(_ _)>
關於(b) 我覺得應該是 Ｃ（下標CaF2）= [CaF2] + [CaF+] + [Ca2+]
不知道這樣寫對不對 ＞ ＜
感謝大家！！！
