Question

What is a Bronsted Base?

Answer 1

Brönsted base

• "According to Brönsted-Lowry theory, bases are substances capable of accepting a hydrogen ion, $\left({\mathrm{H}}^{+}\right)$."
• Brönsted base is commonly classified as a proton acceptor.

Examples

• Ammonia $\left({\mathrm{NH}}_3\right)$ is a bronsted base, as it can accept a proton to form an ammonium ion $\left({{\mathrm{NH}}_4}^{+}\right)$.
• Water $\left({\mathrm{H}}_2\mathrm{O}\right)$ is a bronsted base, as it can accept a proton to form a hydronium ion $\left({\mathrm{H}}_3{\mathrm{O}}^{+}\right)$.
