SOLUBILITY RULES

RULE #1

ALL solutions containing Na⁺¹, K⁺¹, H⁺¹, or NH⁺¹ are ALWAYS soluble. 

Examples: NaClO₃, KCl, HF, o NH₄OH

RULE #2

ALL solutions containing C₂H₃O₂^-1, NO₃^-1,or ClO₃^-1 are ALWAYS soluble.

Examples: Ca(C₂H₃O₂)₂ or Ba(NO₃)₂ or Mg(ClO₃)₂

RULE #3

MOST Chlorides, Bromides, and Iodides are soluble EXCEPT Ag^-1 and Pb⁺²

Example: MgCl₂ or CuI are soluble BUT AgCl (white) or PbI₂ (yellow) are insoluble.
