Question

When a metal X is treated with cold water, it gives a base Y with molecular formula

XOH (molecular mass=40) and liberates a gas Z which easily catches​

Answer 1

Answer:

• Sodium (Na) and potassium (K) react with cold water to form basic salt NaOH and KOH respectively. The molecular mass of NaOH is 40. So, X is Na and Y is NaOH.
