Question

difference between strong acid and weak acid atleat 5 points (class10)

Answer 1

Strong Acid:

Strong acids will dissociate completely to produce H+ ions.
pH values will be around 0 to 1.
Most of the inorganic acids are strong acids in nature.
Ex: H2SO4, HNO3, HCl…etc.

Weak Acid:

Weak acids will dissociate partially to produce H+ions.
pH values will be around 5 to 7.
All organic acids are weak acids.
Ex: CH3COOH, HNO2, H2SO3…etc

Answer 2

Strong Acid ::
1. Acids which dissociate to a large extent in a solution are called strong acids.
2. Almost all their acid molecule break up to form hydrogen ions .
3. HNO3 = EX.
Weak acids ::
1. Acids which undergoes ionisation to a small extent only
2. Only some of their molecules break up to form hydrogen ions
3. CH3COOH =EX.
