Question 3(Multiple Choice Worth 4 points)

(08.04 LC)

Which of the following happens to an acid when it reacts with another substance?

It receives a hydrogen ion.
It receives a hydroxide ion.
It donates a hydroxide ion.
It donates a hydrogen ion.

Answer 1

It donates a hydrogen ion

Step-by-step explanation:

Under the Bronsted-Lowry definition of an acid, acids are protons donors which donate the H+ ion, or the hydrogen ion.

Answer 2

The correct option is "it donates a hydrogen ion"

Step-by-step explanation:

The choice for the last option being the correct answer is because of the Bronsted-Lowry definition of an acid. Bronsted-Lowry acid is a substance that donates a hydrogen ion or a proton.

Consider the reaction below

HCl + NH₃ ⇒ NH₄⁺ + Cl⁻

From the above, we can see that HCl is an example of Bronsted-lowry acid since it donates its hydrogen ion to NH₃ to form NH₄⁺
