Question

Q. How are bases different from alkalis ? Are all bases alkalis ?​

Answer 1

Answer:

Main difference is that bases that dissolve in water are called alkalis and bases that don't dissolve in water are only bases not alkalis, so we can say all bases are not alkali but all alkalis are bases. ... Bases(NaOH) neutralize acids and alkali(CuO) releases hydroxide ions and accepts a proton

Answer 2

Answer:

All bases are not Alkalis

Explanation:

Bases are a class of compounds belonging to the oxides or hydroxides of metal or metal like radicals. On the other hand, bases which are soluble in water are called Alkalis. So Alkalis are water soluble hydroxides of metals.

e.g:- NaOH, KOH are water soluble hydroxides. So they are Alkalis. Therefore Alkalis must be bases. On the other hand, hydroxides of iron fe(OH)3, Al(OH)3 are insoluble in water. So their metallic hydroxides are not Alkalis but they are bases. So all Alkalis are bas s but all bases are not Alkalis.
