How are bases different from alkalis ? Are all bases alkalis ?

Answer»

Solution :Bases which are soluble in water and produce `OH^-` IONS are called alkalis. Some EXAMPLES are : `NAOH rarr Na^+ OH^-`
Potassium hydroxide `KOH rarr K^(+) + OH^(-)`
All alkalis are bases but all bases are not alkalis.
For examples `Al(OH)_(3)` is BASE but not an alkali.
