WebBy starting the reaction, the match will consume oxygen to form carbon dioxide and water. The oxygen is necessary for the reaction to continue. Proof of this can be seen by closing … WebAdd 0.5 g of potassium permanganate powder. If larger sample sizes are used, increase the amount of potassium permanganate so that the ratio of oil to potassium permanganate is still 1:1. Mix the oil and permanganate thoroughly until homogeneous. Thick oils and tars that cannot be mixed should be heated to achieve mixing (the oil may react mildly). fishweir park https://fredlenhardt.net
