Name some common alkalis and bases which will be useful for exams ?10 each​

Answer 1

Bases - sodium oxide , calcium oxide , ammonium hydroxide

Alkali - sodium hydroxide , potassium hydroxide,

Explanation:

Bases that are soluble in water are called alkali. Hence, all alkalis are bases but not all bases are alkalis.

Answer 2

Explanation:

$\huge\underline\pink{Answer}$

→⠀⠀⠀⠀BASES :

Bases have properties that mostly contrast with those of acids.

Aqueous solutions of bases are also electrolytes. Bases can be either strong or weak, just as acids can.

Bases often have a bitter taste and are found in foods less frequently than acids. Many bases, like soaps, are slippery to the touch.

Bases also change the color of indicators. Litmus turns blue in the presence of a base, while phenolphthalein turns pink.

Bases do not react with metals in the way that acids do.

Bases react with acids to produce a salt and water.
