Answer:

1) Strong acid dissociate completely in water , the resulting base formed would be very weak .

2) Because it has less tendency to gain proton i.e strong acids having very weak conjugate base .

Example :- HCl4 ==> ClO4^- + H^+

HCl4 is a strong acid and its conjugate base ClO4^- has less tendency to gain proton. Hence it is a weak conjugate base .

3) Weak acid dissociate completely incompletely in water , the resulting base formed would be very strong.

4) Because it has more tendency to gain proton i.e weak acids have strong conjugate base .

Example :- CH3COOH <==> CHCOO^- + H^+

CH3COOH is a weak acid and its conjugate base CH3COO^- has more tendency to gain proton. Hence it is a strong conjugate base .

If an acid is strong , it's conjugate base will be weak .

HCl is a stronger acid than the H3O+ ion implies that the Cl- ion is a weaker base for the reaction between HCl and water can be written as follows .

if an acid is weak , it's conjugate base will be strong .

A weak acid will have a low concentration of H+ .
