Є декілька в класифікації солей:

За кислотою, якій відповідає ця сіль (хлориди, фосфати, нітрати)

За середовищем : Середні (нормальні) солі, Кислі солі, Основні солі

Солі за своїм складом поділяються на середні, кислі, основні та подвійні.

· середні (нормальні);

Утворюються при повному заміщенні атомів Гідрогену в молекулах кислот атомами металів. Наприклад, Na2CO3, BaCl2.

· кислі;

Утворюються при неповному заміщенні атомів Гідрогену в молекулах кислот атомами металів. Наприклад, NaHCO3, KH2PO­4.

· основні;

Утворюються при неповному заміщенні гідроксильних груп в молекулах основ кислотними залишками. Наприклад, MgOHCl, BaOHBr.

· подвійні;

Утворюються при заміщенні атомів Гідрогену в молекулах кислот двома різними металами. Наприклад, KAlSO4, K2NaPO4.
