2. Define and give emaple of mono-acidic base, a di-acidic base, and a tri-acidic base.?

Answer 1

mono-acidic - It means that the base can accept only 1 proton. . like NaOH and not like Ca(OH)2

Answer 2

Monoacidic base
A base which can accept 1 proton per molecule of base
e.g. NaOH

NaOH + H+(aq) -> Na+(aq) + H2O

Di-Acidic base
A base which can accept 2 protons per molecule of base
e.g. Ca(OH)2

Ca(OH)2 + 2H+(aq) -> Ca++(aq) + 2 H2O

Tri-Acidic base
A base which can accept 3 protons per molecule of base
e.g. Al(OH)3

Al(OH)3 + 3H+(aq) -> Al+++(aq) + 3H2O
