Determine whether each of the following is a strong acid, a weak acid, or a species with negligible acidity.Drag the appropriate
sp2606 [1]

Answer:

CH₃NH₃⁺ is a weak acid.

HPO₄²⁻ has a negligible acidity.

CH₄ has a negligible acidity.

HNO₂ is a weak acid.

Explanation:

There are 7 strong acids: HCl, HBr, HI, HNO₃, H₂SO₄, HClO₃, HClO₄. The rest of the acids are weak.

CH₃NH₃⁺ is a weak acid, according to the following equation:

CH₃NH₃⁺ ⇄ CH₃NH₂ + H⁺

HPO₄²⁻ can act as an acid or as a base:

<u>Acid reaction:</u> HPO₄²⁻ ⇄ PO₄³⁻ + H⁺

<u>Basic reaction:</u> HPO₄² + H₂O ⇄ H₂PO₄⁻ + OH⁻

Given Kb > Ka,  HPO₄²⁻ has a negligible acidity.

CH₄ cannot release nor accept H⁺ so it has a negligible acidity.

HNO₂ is a weak acid, according to the following reaction:

HNO₂ ⇄ H⁺ + NO₂⁻
