Explain with an example that strong acids have very weak conjugate bases and a strong base have a very weak conjugate acid.

Answer»

HCl + HOH -------->  Cl- + H3O+ 

CH3COOH + HOH -------->  CH3COO- + H3O+ 

HCl is strong acid but chloride ion is a weak base similarly CH3COOH is weak acid but CH3COO- ion is a strong base, these example shows that every strong acid has a weak conjugate base and weak acid has a strong conjugate acid.
