alkaline 对应名词 alkali
basic 对应名词 base
The terms "base" and "alkali" are often used interchangeably, particularly outside the context of chemistry and chemical engineering.
There are various, more specific definitions for the concept of an alkali. Alkalis are usually defined as a subset of the bases. One of two subsets is commonly chosen.
1. A basic salt of an alkali metal or alkaline earth metal[2] (this includes Mg(OH)2 (magnesium hydroxide) but excludes NH3 (ammonia)).
2. Any base that is soluble in water and forms hydroxide ions[3][4] or the solution of a base in water.[5] (This includes both Mg(OH)2 and NH3, which forms NH4OH.)
base 是怎么定义的呢?自己看书去。 |
