Question

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,form if acid,sulphuric acid

Answer 1

Acid which is completely ionized in water and produces a large amount of hydrogen ions are called strong acid.
Acid which is partially ionized in water and produces a small as amount of hydrogen ions are called weak acid

hydrochloric acid, nitric acid, sulphuric acid are strong acid whearas acetic acid, formic acid, citric acid are weak acid

Answer 2

Answer: Strong acids are those acids which ionize 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 ionize 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.
