Question

what do you understand by the strength of an acid ?on which factor does the strength of an acid depend?

Answer 1

The strength of acid means amount of hydrogen ions present in an aqueous solution.. It depends on concentration of hydrogen ions and is inversly proportionality to it...

Answer 2

The strength of an acid is the amount of Hydrogen ions it forms when it ionises. It depends on the number of Hydrogen ions [H] and is directly proportional to it. For instance, HCl fully ionises in water so it is a strong acid but Acetic acid partially ionises in water so it is a weak acid.

Hope it helped. Good luck.
