--Acid is the substance when dissolved in water, increases the concentration of H+ ions.

--Such compound whose chemical formula begins with H, for example HCl (Hydrochloric acid), H3BO3 (Boric acid), CH2O3 (Carbonic

--Its less than 7.

--Bases are the proton acceptor.

--Such compounds whose chemical formula ends with OH, for example KOH (Potassium hydroxide), NaOH (Sodium hydroxide).

--Its greater than 7.
