Question

An alkali metal A gives
ses a
compound B (moleculare mass=40)
on reacting with water. The
compound B Gues a soluble
combound c on treatment with
aluminium oxide Identify A, B
and c and gives the reaction ​

Answer 1

Answer:

A is sodium because molar mass of NaOH is 40; which can be shown as follows:

Na(23)+O(16)+H(I)=40

So. B is NaOH

When sodium hydroxide is treated with aluminium oxide, we get sodium aluminate. So, C is sodium aluminate. Following reaction happens in this case:

Al²0³+2NaA1O²+H²O
