Classify each of the follow species as bronsted lowry acid or base NH3,NCN
NH3 is a B-L base. If that is HCN it is an acid.
To classify each species as a Bronsted-Lowry acid or base, we need to understand the Bronsted-Lowry theory. According to this theory, an acid is a substance that donates a proton (H+), while a base is a substance that accepts a proton.
1. NH3 (Ammonia):
To determine whether NH3 acts as an acid or a base, we need to see if it donates or accepts protons. In the case of NH3, it can accept a proton, making it a base. Ammonia is a weak base because it can accept a proton from a stronger acid and form its conjugate acid (NH4+).
2. NCN (Cyanogen):
To determine whether NCN acts as an acid or a base, we once again need to see if it donates or accepts protons. NCN can donate a proton, which means it acts as an acid. Cyanogen is a weak acid as it can donate a proton to a stronger base and form its conjugate base (CN-).
So, to summarize:
- NH3 (Ammonia) is a base.
- NCN (Cyanogen) is an acid.
