Unformatted text preview: F-+ H 2 O HF + F- If you have a basic solution, not much HF forms. The solubility is normal. If you have an acidic solution, F-+ H 3 O + HF + H 2 O Removes F-from equil more soluble than predicted. General Chemistry Lecture 102a In class notes for December 12, 2007 Anions that do not hydrolyze (Cl-, Br-, I-, SO 4 2-to some extent) have not pH dependent solubility. Anions that do hydrolyze have a pH dependent solubility. F-, CO 3 2-, etc. AgCl does not have a pH dependence of solubility. Demostrations...
