Answer 1

Answer:

An acid is a molecule or ion capable of donating a proton, or, alternatively, capable of forming a covalent bond with an electron pair. The first category of acids are the proton donors, or Brønsted–Lowry acids.

Answer 2

Answer:

An acid is any hydrogen-containing substance that is capable of donating a proton (hydrogen ion) to another substance. A base is a molecule or ion able to accept a hydrogen ion from an acid. Acidic substances are usually identified by their sour taste
