The ethyne will REDUCE the permanganate. Just lượt thích what happens in any other redox reaction, each one affects the other. Because it’s acidified the KMnO4 is a more aggressive oxidant và the reaction will proceed at a higher rate of speed. This will happen with ethene as well ethyne, but the ethyne will be more reactive.
The net reaction to the permanganate is that it is reduced from the +7 oxidation state khổng lồ the +4 of manganese dioxide (MnO2 ,which gives the brown/yellow colour these reactions are famous for), or, depending on the acidity, temperature and concentration it will be further reduced to manganese (II) ion- Mn2+, which is colourless. In the process the potassium ion is typically lost lớn the acidic solvent.
Of course, the net reaction also involves the ethyne being oxidised. The fully oxidized product resulting from ethyne is oxalic acid, which permanganate will then further break down khổng lồ give a predominant sản phẩm of carbon dioxide (it may also break the triple bond initially giving the same result) depending on concentration và temperature.

The ethyne will REDUCE the permanganate. Just lượt thích what happens in any other redox reaction, each one affects the other. Because it’s acidified the KMnO4 is a more aggressive oxidant & the reaction will proceed at a higher rate of speed. This will happen with ethene as well ethyne, but the ethyne will be more reactive.
