What is acidity?

Most people know that pH is a measure of acidity, but what is acidity? Well, the Brønsted-Lowry theory states that an acid is a chemical that donates a proton (H+), while a base is a chemical that accepts a proton. The Lewis theory defines acids as chemicals that accept electrons, which is often, but not always, the same thing. For our purposes, acids are chemicals that can donate a proton, while bases (or alkaline substances) are chemicals that accept a proton.

Amino acids in Chinese

Table of amino acids in Chinese

When looking up the word for acid in Chinese, I came across the Chinese for the amino acids. Since I've previously written about DNA and the bases in Chinese, it seemed logical to compile a list of the Chinese amino acids. Working out the logic behind the Chinese words took quite a lot of research, but was very rewarding. Hopefully the effort will help me remember the words.
