Unformatted text preview: 3. Hydrated Metal Ions as Bronsted Acids (proton donors). 4. The Effect of pH on Solubility. (Another application of Le Chatelliers Principle.) Give NIE for these mixtures. The solid in each case is only slightly soluble in water. (a) Mg(OH) 2 (s) + HCl(aq) (b) Mg(OH) 2 (s) + HAc(aq) (c) CaCO 3 (s) + HCl(aq) (d) CaCO 3 (s) + HAc(aq) (e) AgCl (s) + HNO 3 (aq) (f) Ca 3 (PO 4 ) 2 (s) + HAc(aq) Please bring this page to discussion this week. We will have more to do with this....
