Question

According to Reference Table Adv-8, which of the following is the strongest Brönsted-Lowry acid?

1.HS-
2.H2S
3.HNO2
4.HNO3​

Answer 1

HNO3 (nitric acid) is the strongest Brönsted-Lowry acid from the given options, with a pKa value less than zero, indicating a strong tendency to lose a proton.

Step-by-step explanation:

According to Reference Table Adv-8, the strongest Brönsted-Lowry acid from the options given is HNO3 (nitric acid). This conclusion is based on the fact that nitric acid has a pKa value less than zero, which implies that it is a stronger acid than the hydronium ion (H3O+). As a strong acid, HNO3 dissociates completely in water to form hydrogen ions (H+) and its conjugate base, NO3-. This acid is well known for its high tendency to lose a proton, making it a strong Brönsted-Lowry acid in comparison to weaker acids such as HS-, H2S, and HNO2.

Answer 2

HNO3

Step-by-step explanation:

The ability of an acid to act as a Brownstead-Lowry acid depends on it's proton donation ability.

A Brownstead-Lowry acid is a specie that donates hydrogen ions in solution.

Considering all the chemical species listed among the options, HNO3 has the greatest hydrogen donation ability. It then follows that HNO3 is the strongest Brownstead-Lowry acid among the species listed.
