[交流] 中文都叫“碱”,但在英文中,“base”和“alkali“有什么区别呢?

如题。

看看维基对alkali的解释
In chemistry, an alkali  is a basic, ionic salt of an alkali metal or alkaline earth metal element. Some authors also define an alkali as a base that dissolves in water.

Difference between alkali and base

The terms "base" and "alkali" are often used interchangeably, particularly outside of a scientific context.

There are various definitions for alkali. Alkali is often defined as a subset of base. However, two subsets are commonly chosen.
A basic salt of an alkali metal or alkaline earth metal[2] (This includes Mg(OH)2 but excludes NH3.)
Any base that is water-soluble and forms hydroxide ions[3][4][5] or the solution of a base in water.[6] (This excludes Mg(OH)2 but includes NH3.)

The second subset of base is also called an Arrhenius base.
