Read the paragraph and answer the questions following it. Metal oxides are 1 point
basic in nature. Some metallic oxides get dissolved in water and form
alkalis. Their aqueous solution turns red litmus blue. Most metal oxides are
insoluble in water but some of these dissolves in water to form alkalis. .
Sodium oxide and potassium oxide dissolve in water to produce alkalis as
follows Na O(s)+H2O(1) ----2NaOH(aq) K2O(s)+H2O(1) 2KOH(aq) Most of the
metal oxides are basic in nature i.e. they dissolve in water to give an
alkaline solution or they react with an acid to form salt and water. Non-
metals also form respective oxides when reacting with oxygen. What is the
chemical nature of Non-metallic oxides like CO2, NO2,SO, and SO: ?

Since the oxide turns red litmus blue, therefore X is a metal because it is an alkaline oxide.
Most of the metals form respective metal oxides when react with oxygen.
Metal + Oxygen → metal oxide
Examples: (1) Reaction of potassium with oxygen:- Potassium metal forms potassium oxide when reacts with oxygen.
4K+O

→2K

(2) Reaction of sodium with oxygen:- Sodium metal forms sodium oxide when reacts with oxygen.
4Na+O

→2Na
