Question

What are alkalies ?​

Answer 1

Answer:

Alkali, any of the soluble hydroxides of the alkali metals—i.e., lithium, sodium, potassium, rubidium, and cesium. Alkalies are strong bases that turn litmus paper from red to blue; they react with acids to yield neutral salts; and they are caustic and in concentrated form are corrosive to organic tissues.

Answer 2

The bases which are highly soluble in water are called alkali. e.g. NaOH, KOH, NH3. Here, NaOH and KOH are strong alkalies while NH3 is a weak alkali.
