Question

How will you prove that the oxide of a non-metal like SO2 is acidic in nature?

Answer 1

Answer:

When we dip red litmus paper to one of the test tubes containing magnesium oxide solution then there is no change in colour. When we dip blue litmus paper to another test tube containing magnesium oxide solution then we see that blue litmus paper turns red. We know that only acidic substances turn blue litmus to red.

hope it helps

Answer 2

Answer:

When non metallic oxide for example SO2 (non metal) is dissolved in water it produces sulphurous acid which is acidic in nature. When metallic oxide (metal) reacts with water it produces metal hydroxides that are basic in nature. ... In the case of sulphurous acid, the blue litmus turns red indicating that it is acidic.
