How can we know that why acid and bases are weak and strong

1.	How can we know that why acid and bases are weak and strong
Answer» Saloni you are right ? With the use of pH paper or universal indicators This statement could be justified by the release of hydorhen ions jn aques soln by acids and bases. Acids amd bases nwhich produce more h² ions are strong. Amd those who produce less h2 are weak. Those acid and bases have completely ionised in aquous solution are strong acid or bases and those acid or base who does not ionised in (aq) solution are weak acid or base.
