Sulphur Dioxide forms an acid | Acids & Bases | Chemistry

If we leave a glass of water in the open air for a few days, the water will turn it slightly acidic. This happens because the gaseous carbon dioxide in air dissolves in water to form carbonic acid. Like carbon dioxide, which is an oxide of a non-metallic element (Carbon), this property is also true generally true for oxides of other non-metals. The video demonstrates the heating of sulphur in a test tube until it oxidizes (burns) and releases sulphur dioxide smoke. Sulphur dioxide does not affect red litmus but changes the colour of wet blue litmus paper to red, showing us that sulphur dioxide gas is acidic. Sulphuric acid is produced by dissolving sulphur dioxide in water. Many industrial processes produce sulphur dioxide gas as a pollutant and when this gas dissolves in rain water, we get acid rain which is harmful to the biosphere.

Noice sir u explained very nicely.
Thank u sir!

[superboy]

Thank you .. very nicely explained I liked it

[annuDiiiii]

Thank u for ur explanation sir I was confused now I understand I was confused how does it isn't turns red to blue but now I knew the answer thxx sir :)

[omsingharjit]

Can so3 be prepared by heating sulphur ?

[pushkarjoshi]

Please show how sulphur TRIoxide reacts with water to form sulphuric acid

[Saumiiiii]

I know this is a late message, but wouldn't Sulfur Dioxide react with water to form Sulfurous Acid (H2SO3), or am I wrong in this?


SO2 + H2O H2SO3 ??

[moddassirkhan]

Sir you are the best teacher in the world thanku sir

[LUCIFER-yobz]

Hlo sir
I am piyush
Can you make the video of reaction with water of metal

[moddassirkhan]

sir plz upload video all about TEST OF PH OF GIVEN SAMPLE BY LITMUS PAPER practical video explain it brèefly plz sir

[wenzyrose]

Why did the reaction produce sulfuric acid (H2SO4) and not sulfurous acid (H2SO3)?

SO2 + H2O = H2SO3? Correct me if I'm wrong.

my coconut water contains suphurdioxide

I can't concentrate watching him at first bcoz of the rubics cube on his table. it's not solved and it's making me uncomfortable ugghhh....
