What are strong and weak acids? In the following list of acids separate strong acids from weak acids . Hydrochloric acid, citric acid , acetic acid, nitric acid formic acid , suphuric acid.

Explanation

Strong acids are those acids which ionise almost completely in aqueous solution and hence produce a large amount of `H^(+)` ions and therefore , conduct electricity to a large extent. Weak acids are those acids which ionise to a small extent in the aqueous solution and hence produce a small amount of `H^(+)` ions and therefore conduct electricity to a small extent .
Strong acids : Hydrochloric acid , nitric acid sulphuric acid .
Weak acids : Citric acid , acetic acid , formic acid .
