[Restless Ion]

Hello,

I'm having some trouble figuring out the exact reaction between acetylen and potassium permanganate in an acidic solution (sulfuric (VI) acid). The purpose of this experiment is to verify the unsaturated nature of acetylen. During the formation of the products, the standard permanganate violet disappeared and in it's place the solution remained colourless. Now,  the permanganate in an acidic solution is a strong oxidant, so I think this should lead to the oxidation of acetylen and therefore the formation of metanoic acid HCOOH and carbon dioxide, since this is a standard baeyer's test and something similar happens with alkenes, while the same reaction in an alkaline environment would have produced acetic acid. Therefore, the reaction would basically amount to:

C₂H₂ + (O) H-COOH + CO₂

Is this correct?
