For The Reaction CH3COOH ---> CH3COO- + H+, which of the following statements is true? A.) Ch3COOH is a Bronsted Lowry base.

Savatey [412]

Answer: Option (C) is the correct answer.

Explanation:

According to Arrhenius, bases are the species which when dissolved in water will give hydroxide ions, that is, $OH^{-}$ .

For example, $NaOH + H_{2}O \rightarrow Na^{+} + OH^{-}$

Arrhenius acids are the species which when dissolved in water will give hydrogen ions, that is, $H^{+}$ .

For example, $CH_{3}COOH + H_{2}O \rightleftharpoons H_{3}O^{+} + CH_{3}COO^{-}$

In water, when an acid loses a hydrogen ion then the specie formed is known as conjugate base.

Here, $CH_{3}COO^{-}$ is the conjugate base of $CH_{3}COOH$ .

Similarly, species which accept the hydrogen ion result in the formation of conjugate acid.

Hence, $H_{3}O^{+}$ is the conjugate acid of $H_{2}O$ .

Thus, we can conclude that $CH_{3}COO^{-}$ is the conjugate base.

Write a chemical equation showing how each behaves as an acid when dissoblbed in water.

nikdorinn [45]

Answer:

a. H₂S(aq) + H₂O(l) ⇄ HS⁻(aq) + H₃O⁺(aq)

b. NH₄⁺(aq) + H₂O(l) ⇄ NH₃(aq) + H₃O⁺(aq)

Explanation:

According to Bronsted-Lowry acid-base theory,

An acid is a substance that donates a H⁺.

A base is a substance that accepts a H⁺.

a. When dissolved in water, H₂S behaves as an acid according to the following equation.

H₂S(aq) + H₂O(l) ⇄ HS⁻(aq) + H₃O⁺(aq)

b. When dissolved in water, NH₄⁺ behaves as an acid according to the following equation.

NH₄⁺(aq) + H₂O(l) ⇄ NH₃(aq) + H₃O⁺(aq)
