Question

a carbon compound x produces a compound y on oxidation with acidified pottasium permanganate.on reaction with sodium carbonate y produces a gas which turns lime water milky. find x and y​

Answer 1

Answer:

SO

2

is a colourless suffocating gas. Acidified potassium manganate(VII) is a strong oxidising agent so it can be used to oxidise substances. If a reaction occurs a colour change will be seen. Potassium manganate(VII) is deep purple and when it is reduced, it becomes colourless.

If sulphur dioxide gas is bubbled into the purple acidified manganate(VII) solution, the manganate(VII) is decolourised showing that the manganate(VII) ions are being reduced by the sulphur dioxide gas to Mn

ions.
