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.
