Question

define strong and weak acids. classify the following as strong and weak acids: hydrochloric acid, acetic acid, hydrofluoric acid, nitric acid, with the help of chemical equation show the reactiob of acids with metals

Answer 1

Here is your answer :-

✔ Strong Acids :- those acids which completely ionised and give more H+ ions .

✔Weak Acids :- those acids which incompletely ionised and give less H+ ions .

✔ Hydrochloric acid , sulphuric acid and nitric acid are strong acids

✔ acetic acid and hydrofluoric acid is weak acids

✔ when metal react with acids , it forms salt and evolve hydrogen gas
example :-
2HCl + 2Na ---------> 2NaCl + H2
