A basic salt is formed in the reaction of neutralization between a weak acid and a strong base. For example, C₆H₅COOLi is a product of neutralization reaction between C₆H₅COOH and LiOH. C₆H₅COOH is a weak acid and LiOH is a strong base. Hence, C₆H₅COOLi is a basic salt.

Another way to look at this: a basic salt is made of a cation, which is a Bronstead-Lowry acid of negligible strength (not an acid), and an anion, which is a weak Bronstead-Lowry base. For example, C₆H₅COO^- is a weak base. Li⁺ has negligible strength as an acid (not an acid). Hence, C₆H₅COOLi is a basic salt.
