Question

an alkali matel A gives a compond B(molecular mass 40amu)on reacting with water the compond B gives a soluble compound C on treatment with aluminium oxide identify A,B,C
​

Answer 1

Answer:

When it reacts with water, it forms a compound B having molecular mass 40. ... So, compound B is sodium hydroxide (NaOH) Sodium hydroxde reacts with aluminium oxide (Al2O3) to give sodium aluminate (NaAlO2). Thus, C is sodium aluminate (NaAlO2).
