Question

can anyone explain me about the acids

Answer 1

An acid is a molecule or ion capable of donating a proton (hydrogen ion H+) (a Brønsted–Lowry acid), or, alternatively, capable of forming a covalent bond with an electron pair (a Lewis acid).

The first category of acids are the proton donors, or Brønsted–Lowry acids.

In the special case of aqueous solutions, proton donors form the hydronium ion H3O+ and are known as Arrhenius acids
