Question

Label each reactant in the reaction below as a proton donor or a proton acceptor and as acidic or basic H2Co3 +H20---------HC0-3+h30+

Answer 1

Answer:

Proton donor - H2CO3

Proton acceptor - H2O

Explanation:

The balanced reaction is

H2CO3 +H2O---------HCO3 - + h3O+

Here, water molecule i.e H2O has one additional H + ion hence it has accepted the hydrogen atom.

This additional hydrogen atom has been donated by H2CO3 thereby reducing itself to HCO3-

Hence,

Proton donor - H2CO3

Proton acceptor - H2O

Answer 2

In the given reaction, a proton donor is H₂CO₃ and proton acceptor is H₂O.

What is Bronsted-Lowry theory?

Bronsted-Lowry theory states that those substances which gives proton or (H⁺ ion) are known as acids and those which accepts proton or (H⁺ ion) are known as bases.

Given chemical reaction is:

H₂CO₃ + H₂O → HCO₃⁻ + H₃O⁺

In the above reaction H₂CO₃ gives H⁺ ion to the water molecule and H₂O accepts H⁺ ion for the formation of HCO₃⁻ & H₃O⁺. So, H₂CO₃ is a proton donor and behaves as acid and H₂O is a proton acceptor and behaves as base.

Hence, H₂CO₃ is a proton donor and H₂O is a proton acceptor.
