Question

classify the following acid on the basis of mono basic dia basic and tria basic acids,HCL, HNO3, HCSO4,H3BO3, H3PO4​

Answer 1

$\large\underline{\underline{\red{\sf\blue{\dag}\:Before\:we\:procced\:we\:must\:know,}}}$

$\underline{\tt{\green{\leadsto Monobasic\:Acid:-}}}$

• Acids that contain only one replaceable hydrogen per molecule that is produce only one hydronium ion per molecule in the solution.

$\underline{\tt{\pink{\leadsto Dibasic\:Acid:-}}}$

• Acids that contain only two replaceable hydrogen per molecule that is produce two hydronium ion per molecule in the solution.

$\underline{\tt{\purple{\leadsto Tribasic\:Acid:-}}}$

Acids that contain three replaceable hydrogen per molecule that is produce three hydronium ion per molecule in the solution.

$\large\underline{\underline{\red{\sf\blue{\dag}\: Required\: Solution:-}}}$

Given acids are ,

• $\sf HCl$
• $\sf HNO_3$
• $\sf H_2SO_4$
• $\sf H_3BO_3$
• $\sf H_3PO_4$

✤ $\sf HCl,HNO_3\:\&\:H_3BO_3$have basicity 1 . Hence they are monobasic acid . Hydrochloric Acid and Nitic acid release one H+ ion in water , whereas Boric acid is OH- ion acceptor .

✤ Here , Sulphuric acid is a dibasic acid since it release two H+ ions in water .

$\boxed{\tt{\pink{ \underset{\blue{Sulphuric\:acid}}{H_2SO_4}+\underset{\blue{Water}}{H_2O}\longrightarrow 2H^+ + SO_4^{2-}}}}$

✤ Here , Orthophosphoric acid has three replaceable hydrogen ions , so it has a basisity of 3 and hence is a tribasic acid.

➳ Hence Here ,

$\sf\orange {Monobasic\:Acid}\:-\:HCl,HNO_3,H_3BO_3$

$\sf\orange {Dibasic\:Acid}\:-\:H_2SO_4,$

$\sf\orange {Tribasic\:Acid}\:-\:H_3PO_4$
