Question

explain the similarity and difference in two events namely adding naoh to water and addind caoh to water

Answer 1

similarities :
they both are exothermic in nature ...
they both formed strong alkali ....
Difference :
NaOH combine to form Na + ion and
OH - ion .Cao combine with water to form calcium hydroxide ...
NaOH is monoacidic in nature and CaOH is diacidic in nature ....

Answer 2

Answer:

Chemical equations :

1. NaOH + H2O ---> NaOH + Heat
2. CaO + H2O ---> CA(OH)2 + Heat

Explanation:

Similarity :-

• Both equations are exothermic. It means a lot of heat is evolved during the reaction.
• Both reactions Form strong basic solution.

Difference :-

• NaOH is monoacidic base and CaO is diacidic base.
• NaOH , CaO should be added to water gradually with constant stirring.

Hope this helps you...
