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.

HCl ----> H+ + Cl- (complete dissociation)

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

HNO2 -----> H+ + NO2 - (partial dissociation)
