Acid Roots Mnemonic

Monovalent ammonium nitrate; hydrochloric acid hydroxide.

Permanganate chlorate; perchlorate acetate.

Divalent sulfate carbonate; sulfite manganate.

Tentatively the ammonium root is positive; minus three has a phosphate root.

These are common acid root valence, should be noted that the mnemonic "a price", only the ammonium root is positive, the rest are negative.

Negative one nitrate hydroxide, negative two carbonate sulfate, negative three remember phosphate.
