is the gas from potassium permangunate and glycerol poisioness??? or what gas is formed

KMnO4 is a oxidising agent, and glycerol is an alcohol.

if u've studied organic chemistry, then u'll know that alcohols are oxidised to carboxylic acids.

no gases are formed, and no toxic substances are formed.

Depending on amount of permanganate, in acidic solution glycerol can be oxidised up to CO2.
Concentration of CO2 over 1% (V/V) in air is dangerous for humans.

So its Concentrated CO2

14KMnO4 + 5C3H8O3 + 21H2SO4 = 7K2SO4 + 14MnSO4 + 15CO2(g) + 41H2O

primary alcohols are oxydized to carboxylic acids
some oxydizing agent like PCC convert it to aldehydes

secondary alcohols are converted to ketones
