Q4 of 30 Page 34

Metal oxides are basic oxides. Explain with an example.

Metal oxides form basic oxides. For example:

When sodium oxide (metal oxide) reacts with water, it forms sodium hydroxide which is a basic oxide. Basic oxide shows basic properties. The reaction is given as:


Na2O + H2O → NaOH


The other example is magnesium oxide:


When magnesium oxide reacts with water, it forms magnesium hydroxide which is a basic oxide and shows all the properties of a base. The reaction is given as:


MgO + H2O → Mg(OH)2

A compound 'X' is constituent of baking powder. It is used as an antacid. When 'X' is heated, it gives out a 'Y' which when passed through lime water turns it milky, and salt 'Z' is formed which is the main constituent of washing powder. Identify X Y and Z. Write balanced chemical equations for the reactions involved.
