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

Engineering Chemistry III Prof. K. M. Muraleedharan Aromatic electrophilic substitution (Ar-SE) Reactions The special reactivity of aromatic systems towards electrophiles arises mainly from two factors: the presence of π electron density above and below the plane of the ring - making it nucleophilic‚ and the drive to regain the aromatic character by opting for substitution as opposed to a simple addition reaction. Preference towards addition reactions in the case of alkenes and substitution

TITLE : The copper cycle IN TRODUCTION The purpose of the experiment is to recognize that change of state‚ change in colour‚ formation of a precipitate‚ or the evolution of heat are associated with a chemical change; to study reactions of copper. Copper is an element that can be found in nature in a variety of different compounds. The most common natural ore is the sulphide‚ known as chalcocite‚ Cu2S. This mineral is an important source of copper metal because it is about 80% copper by

In the second separation of this experiment‚ the Erlenmeyer flask with the first filtrate was put into a beaker so the filtrate was in the beaker. The beaker was then heated on a hotplate until near boiling. After the whey protein had precipitated‚ a vacuum filter was used to filter out the whey. These proteins were then air-dried. A qualitative test was done to indicate that the sample extracted was the protein whey. Again‚ a small test tube was used and 2 mL of protein test solution was put in

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
