Classify these salts as acidic, basic, or neutral. kcl, nh4br, k2co3, nacn, liclo4? this is what i put but got it wrong: nh4br = acidic nacn = basic

I'll just list down the acidic, basic, and neutral salts.

ACIDIC
THE CATION: is the conjugate acid of a weak base
THE ANION: Conjugate Base of A Strong Acid

Ammonium Sulfate - (NH₄)₂SO₄
Ammonium Chloride - NH₄Cl
BASIC
THE CATION: comes from the cation of a strong Base (i.e. Na+, K+, Li+)
The Anion: comes from the conjugate base of a weak acid 

Sodium Acetate - CH₃COONaSodium Phosphate - Na₃PO₄
Calcium Acetate - (CH₃COO)₂Ca
NEUTRAL
THE CATION: comes from a strong base
THE ANION: comes from a strong acid

Sodium Nitrate - NaNO₃
Barium Chloride - BaCl₂Potassium Chloride - KCl

Thermohaline circulation and gyres
