Thank you for your help. I think the differences between my question and the question that you sent me is that: mine is the mixture of H3PO4 and CaCl2 while the other is just dissociation of H3PO4. For b) I just write H3PO4 + H20 -> H2PO4- +H3O+ H2PO4-
Thank you DrBob222. Yes, 0.8661 and 0.8896 are activity coefficients. That is my bad. Thanks to your suggestion, I already figure out the solubility of TISCN is 0.01425. Besides, the solubility would be 0.01265 if I applied the formula S=Ksp ^(1/2). What
Thank you DrBob222. My activity of Ti is 0.8661 and SCN is 0.8896. I do not know any equation between activity and solubility. Can you help me with that? Thank you
