Answer 1

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.

Answer 2

• In the reaction HI(aq) + H₂O(l) → I⁻(aq) + H₃O⁺(aq), HI is a Brønsted−Lowry acid and H₂O a Brønsted−Lowry base.
• In the reaction F⁻(aq) + H₂O(l) ⇌ HF(aq) + OH⁻(aq) , H₂O is a Brønsted−Lowry acid and F⁻ a Brønsted−Lowry base.

Let's consider Brønsted−Lowry acid-base theory:

• An acid is a species that donates H⁺.

• A base is a species that accepts H⁺.

We have 4 equations and we want to identify which reactant is the acid or the base.

What are the reactants?

The substance(s) to the left of the arrow in a chemical equation are called reactants.

Part A. Identify the reactant that is a Brønsted−Lowry acid in the following reaction:

HI(aq) + H₂O(l) → I⁻(aq) + H₃O⁺(aq)

HI donates H⁺ to H₂O, so it is an acid.

Part B. Identify the reactant that is a Brønsted−Lowry base in the following reaction:

HI(aq) + H₂O(l) → I−(aq) + H₃O⁺(aq)

H₂O accepts H⁺ from HI, so it is a base.

Part C. Identify the reactant that is a Brønsted−Lowry acid in the following reaction:

F⁻(aq) + H₂O(l) ⇌ HF(aq) + OH⁻(aq)

H₂O donates H⁺ to F⁻, so it is an acid.

Part D. Identify the reactant that is a Brønsted−Lowry base in the following reaction:

F⁻(aq) + H₂O(l) ⇌ HF(aq) + OH⁻(aq)

F⁻ accepts H⁺ from H₂O, so it is a base.

• In the reaction HI(aq) + H₂O(l) → I⁻(aq) + H₃O⁺(aq), HI is a Brønsted−Lowry acid and H₂O a Brønsted−Lowry base.
• In the reaction F⁻(aq) + H₂O(l) ⇌ HF(aq) + OH⁻(aq) , H₂O is a Brønsted−Lowry acid and F⁻ a Brønsted−Lowry base.
