Identify the acid and base reactants in the following reaction

Answer:

(1) HI is Bronsted-Lowry acid and $H_{2}O$ is Bronsted-Lowry base.

(2) $H_{2}O$ is Bronsted-Lowry acid and $F^{-}$ is Bronsted-Lowry base.

Explanation:

A Bronsted-Lowry acid is a species which donates proton ( $H^{+}$ ).

A Bronsted-Lowry base is a species which accepts proton ( $H^{+}$ ).

(1) $HI(aq)+H_{2}O(l)rightarrow I^{-}(aq)+H_{3}O^{+}(aq)$

Reactants: HI and $H_{2}O$

Here HI donates proton and $H_{2}O$ accepts proton.

Hence HI is Bronsted-Lowry acid and $H_{2}O$ is Bronsted-Lowry base.

(2) $F^{-}(aq)+H_{2}O(l)rightleftharpoons HF(aq)+OH^{-}(aq)$

Reactants: $F^{-}$ and $H_{2}O$

Here $H_{2}O$ donates proton and $F^{-}$ accepts proton.

Hence $H_{2}O$ is Bronsted-Lowry acid and $F^{-}$ is Bronsted-Lowry base.
