Question

Using the Arrhenius concept of acids and bases, identify the Arrhenius acid and base in each of the following reactions: KOH(aq) HNO3(aq)→KNO3(aq) H2O(l) (CH3)3N(g) HI(g)→(CH3)3NHI(s) Drag the appropriate items to their respective bins.

Answer 1

Answer:

Acids:  HNO₃ and HI

Base: KOH

Explanation:

For the Arrhenius concept, acid is a substance that, in water, produces the hydrogen ion (H⁺), and base in the substance that, in water, produces the hydroxyl ion (OH⁻).

For the first reaction then KOH must produce OH⁻ so its a base, and HNO₃ must produce H⁺ so it's an acid.

For the second one, HI must produce H⁺ so it's an acid. For the concept of Arrhenius, (CH₃)₃N can't be classified as a base or as an acid.
