1. Strong and Weak-

Strong Acid/Base Weak Acid/Base
Strong acids and basesare thoseacids or Weak acids and basesare those acids or
bases that completely dissociate to form bases thationize only partially, and the
ions in aqueous solution. ionization reaction is reversible.

So, strong acids and bases ionise So, weak acid and base solutions contain
completely to form the corresponding multiple charged and uncharged species
positive and negative ions.

+ - - +
Example- HCl(aq)  H (aq) + Cl (aq) CH3COOH(aq)  (CH3COO) (aq)+ H (aq)
+ - + -
NaOH(aq)  Na (aq) + (OH) ( aq) NH4OH(aq)  NH4 (aq) + OH (aq)
