Question

perform an activity to test whether nitric oxide and sulphur dioxide are acidic, basic amphoteric or neutral oxides​

Answer 1

HOPE IT HELPS :)

To test for Nitric oxide (NO2) & Sulphur Dioxide (SO2) :

PROCEDURE 1. add this oxide in water drop by drop with constant stirring

2. Now take a blue litmus

3. Observe the changes

OBSERVATION : The blue litmus changes to red

CONCLUSION : Since the blue litmus changes to red it shows the presence of acid .

RESULT : Thus , these oxides are acidic in nature

Explanation:

Since we all know that non-metallic oxides are acidic in nature ...this is a simple activity through which ypu can prove as well

Also instead of blue litmus one caj take other indicators as well like turmeric ,methyl orange etc

For more understanding you can look at the equations below

NO2+H20= HN03( Nitric Acid )

SO2+H20=H2SO4( Sulphuric acid )
