Q4 A given metal sulfide (MS) has very low solubility (K,p = 1x10 30). Keeping in mind that S? is the conjugate base of the diprotic acid H2S (Ka1 = 9.6 x 108, Ka2 = 1.3 x 1014). Calculate the solubility of ZnS in a) A buffer of pH=10.0 b) A solution containing 0.100 M EDTA buffered at pH=10.0 (K; (MY²) = 1.0 x 10 16 at pH=10.0)
