Salts
Part of the Acids and Bases section of Coddy's Chemistry journey. Lesson 20 of 30.
A salt: a positive ion (metal or NH₄⁺) with the negative ion of an acid. NaCl, CaCO₃, CaSO₄.
The charges cancel: Ca²⁺ and NO₃⁻ make Ca(NO₃)₂.
Families: chlorides from HCl, sulfates from H₂SO₄, nitrates from HNO₃, phosphates from H₃PO₄.
