Question

# Assertion : $$HCO_3^-$$ can act as a Bronsted acid or a Bronsted base.Reason : $$HCO_3^-$$ can donate a proton to form $$CO_3^{2-}$$ or accept a proton to form $$H_2CO_3$$.

A
Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
B
Both Assertion and Reason are correct and Reason is not the correct explanation for Assertion
C
Assertion is correct but Reason is incorrect
D
Assertion is incorrect but Reason is correct
E
Both Assertion and Reason are incorrect

Solution

## The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for AssertionA Bronsted acid donates a proton and a Bronsted base accepts a proton.$$HCO_3^-+H^+\longrightarrow H_2CO_3$$  Bronsted base$$HCO_3^-\longrightarrow CO_3^{2-}+H^+$$  Bronsted acidSince, $$HCO_3^-$$ can donate a proton to form $$CO_3^{2-}$$ and can accept a proton to form $$H_2CO_3$$, it can act as a Bronsted acid as well as a Bronsted base. Hence both assertion and reason are correct and reason is the correct explanation for assertion.Chemistry
