Solution: Which one of the following is a Br∅nsted-Lowry acid?     A) HFB) HNO 2C) CH 3COOHD) (CH 33NH +E) all of the above

Solution: Which one of the following is a Br∅nsted-Lowry acid?     A) HFB) HNO 2C) CH 3COOHD) (CH 3) 3NH +E) all of the above

Problem

Which one of the following is a Br∅nsted-Lowry acid?     

A) HF

B) HNO 2

C) CH 3COOH

D) (CH 33NH +

E) all of the above

Solution

We’re being asked to identify which of the given compounds is a Bronsted-Lowry acid


Let’s define a Bronsted-Lowry Acid and a Bronsted-Lowry Base.

Bronsted-Lowry acid → proton (H+) donor

Bronsted-Lowry base → proton (H+) acceptor


A) HF

HF is a weak acid
can dissociate in a solution:
