Definition

A Bronsted-Lowry base is a compound that serves as a proton(H+) acceptor.

Explanation

In a Bronsted-Lowry Base, the compound is able to accept a proton

When we talk about the Bronsted-Lowry reactions, it’s important to think conjugates.

  • A strong base will have a weak conjugate acid.
  • A weak base will have a strong conjugate acid


There are several lists that denote which acids are strong and which are weak. It’s important to know these, especially when more complex reactions are taking place.
