Question

In the reaction NO −(aq) + H O(l) → HNO (aq) + OH−(aq), the NO − acts as

A) an Arrhenius acid B) a Bronsted acid C) an Arrhenius base D) A bronsted base

Answer 1

The answer is D.

Step-by-step explanation:

We have to look at the definitions of Arrhenius acids and bases and Bronsted acids and bases.

Arrhenius acids dissociate in water to produce H⁺ ions, whereas Arrhenius bases dissociate in water to produce OH⁻ ions.

Bronsted acids donate protons and Bronsted bases accept protons.

In this case, NO⁻ does not produce H⁺ or OH⁻ ions in solution. However, NO⁻ becomes the product HNO, which means it accepted an H⁺ ion, making NO⁻ a Bronsted base.
