polyatomics, solubility rules, strong and weak acids/bases, solubility rules

strong acids

hydrochloric acid, hydrobromic acid, hydroiodic acid, perchloric acid, nitric acid, periodic acid, sulfuric acid, chloric acid

solubility rules

1. Most nitrate salts are soluble.

2. Most salts containing alkali metals and ammonium ion are soluble

3. Most chloride, bromide, and iodide salts are soluble except for Ag⁺, Pb²⁺, and Hg₂²⁺

4. Most sulfate salts are soluble except for BaSO4, PbSO4, Hg2SO4, and CaSO4

5. Most hydroxides are insoluble. Important soluble hydroxides are NaOH and KOH.

6. Most sulfide, carbonate, chromate, and phosphate salts are insoluble, except for those containing cations in Rule 2.
