Question

In increasing order of strong acids arrange these acids
H3BO3 or H2CO3 or HNO3

Answer 1

Answer:

Explanation:

HNO₃  = 2.4*10¹

H2CO3  = 4.4*10⁻⁷

H3BO3 = 5.8*10⁻¹⁰

HNO3 >H₂CO₃ >H₃BO₃

Answer 2

The increasing order of strong acids is HNO3 >H₂CO₃ >H₃BO₃

Explanation:

• Acidic salts are those which has acidic replaceable hydrogens in it
• H2CO3 has two acidic hydrogens
• Binary acids are some of the strongest a more electronegative central atom pulls electron density towards itself.
• A larger atom makes a weaker bond with the H;
• HNO3  is a stronger acid than H₂CO₃ and H₃BO₃
• The reason for being a strong acid is that N is more electronegative than  Cl , C or B, because it pulls electron density towards itself better than other. So the Hydrogen attached to an  O, gets less of it and then the O−H bond gets weakened. Thus Weaker bond = stronger acidity.
