what is alkali? give an example
Answers
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.
The term alkali is also applied to the soluble hydroxides of such alkaline-earth metals as calcium, strontium, and barium and also to ammonium hydroxide.
The term was originally applied to the ashes of burned sodium- or potassium-bearing plants, from which the oxides of sodium and potassium could be leached.
