Question

Can Thiocyanic acid, HSCN, can be a Bronsted-Lowry Acid? How about a Bronsted-Lowry Base?

Answer 1

It can be a bronsted Lowry acid but not a bronsted Lowry base

Step-by-step explanation:

Bronsted Lowry acid are proton donors, and HSCN can donate a proton, but it cannot accept a proton, hence not a bronsted Lowry base

Answer 2

Step-by-step explanation:

A Brönsted-Lowry acid is defined as any substance that has the ability to lose, or "donate a proton" [H +].

A Brönsted-Lowry base is a substance capable of gaining or "accepting a proton" [H +].

Then a proton transfer occurs, which requires the presence of a proton donor, that is, an acid and a base that accepts them.

This theory has the disadvantage of leaving out several substances that are acidic and that do not have protons.

Thiocyanic acid is a chemical compound that can be considered, but not a Bronsted Lowry base, giving up the proton and generating the anion [SCN] -
