red. Does anyone know which functional group would be present in solution? Potassium Magante is K2MnO4 whereas the permanganate is KMnO4‚ in the second one the Mn as a higher oxidation state of +7‚ the other one just +6. It would show that a double bond is present. (It oxides the alkene to a diol‚ which changes the oxidation state of the Mn changing it’s colour) Original post by GyasiW) First of all I would like to know the differences in formulae between Potassium Mangante and Potassium Permanganate

If the oxidation number of an atom decreases in a reaction‚ it indicates a gain of electrons. • You can balance an equation by finding the coefficients that make the number of electrons lost by one atom of one element equal to the number of electrons gained

oxygen in the air. Via a free radical process‚ the double bonds of an unsaturated fatty acid can undergo cleavage‚ releasing volatilealdehydes and ketones. This process can be suppressed by the exclusion of oxygen or by the addition of antioxidants. Oxidation primarily occurs with unsaturated fats. Microbial rancidity[edit] Microbial rancidity refers to a process in which microorganisms‚ such as bacteria‚ use their enzymes such as lipases to break down fat. This pathway can be prevented by sterilization

ATP 8.1.1 State that oxidation involves the loss of electrons from an element‚ whereas reduction involves a gain of electrons; and that oxidation frequently involves gaining oxygen or losing hydrogen‚ whereas reduction frequently involves losing oxygen or gaining hydrogen. Oxidation: gain oxygen / lose hydrogen / lose electrons Reduction: lose oxygen / gain hydrogen / gain electrons 8.1.2 Outline the process of glycolysis‚ including phosphorylation‚ lysis‚ oxidation and ATP formation.

antioxidant are used widely in the production of food which fats and oils are used as raw materials and in the marketing of foods containing fats under modern conditions. The major factor in quality degradation of fats and fatty portions of foods is oxidation. In the oxidative deterioration of fats and fat-like substances‚ off-flavors and off-odors are usually reported. Rather than the breakdown of the unsaturated fat molecules‚ there are four types of fat deterioration. Hydrolysis is the formation of

Main factors affect the refined oil yield: 1‚ the alkali refining loss (1) for removal of colloid in hair oil‚ free fatty acid‚ moisture‚ impurities and other form of loss; (2) in the process caused by the loss of neutral oil saponification‚ emulsification; (3) theoretical calculation formula: alkali refining losses = 0.2 + 1.25 x (FFA % % + water + phosphatide content % % + 0.3% + impurities) 2‚ decoloring loss mainly for adsorption bleaching waste clay in oil absorption caused by the loss
