A basic salt is a salt that contains a cation from a weak base and an anion from a strong acid. The only picture that represents a basic salt is (1), which shows the salt sodium acetate (CH3COONa). Sodium acetate is a basic salt because the cation (Na+) comes from the weak base sodium hydroxide (NaOH) and the anion (CH3COO-) comes from the strong acid acetic acid (CH3COOH).
