Chemistry Chapter 4 Review

1) All common compounds of Group 1A(1) ions (Li⁺, Na⁺, K⁺, etc.) and ammonium ion (NH₄⁺) are soluble.

2) All common nitrates (NO₃^-), acetates (CH₃COO^- or C₂H₃O₂^-), and most perchlorates (ClO₄^-) are soluble.

3) All common chlorides (Cl^-), bromides (Br^-), and iodides (I^-) are soluble, except those of Ag⁺, Pb^2+, Cu⁺, and Hg₂²⁺. All common fluroids (F^-) are soluble, except those of Pb²⁺ and Group 2A(2).

4) All common sulfates (SO₄^2-) are soluble, except those of Ca²⁺, Sr²⁺, Ba²⁺, Ag⁺, and Pb²⁺.

1) All common metal hydroxides are insoluble, except those of Group 1A(1) and the larger members of Group 2A(2) (beginning with Ca²⁺).

2) All common carbonates (CO₃^2-) and phosphates (PO₄^3-) are insoluble, except those of Group 1A(1) and NH₄⁺.

3) All common sulfides are insoluble except those of Group 1A(1), Group 2A(2), and NH₄⁺.
