An element X forms two oxides XO and XO₂. The oxide XO has no action on litmus solution but oxide XO₂ turns litmus solution red.
(a) What is the nature of oxide XO?
(b) What is the nature of oxide XO₂?
(c) Would you call element X a metal or a non-metal? Give reason for your choice.
(d) Can you give an example of element like X?

Solution

(a) The oxide XO is neutral in nature as it has no action on litmus solution.

(b) The oxide XO₂ is acidic in nature as it turns litmus solution red.

(c) The element X is a non-metal because it forms an acidic and neutral oxide, which is the property of a non-metal.

(d) Carbon is a non-metal like the element X.
