Pure Compound X has a melting range of 128- 129*C. If you perform a melting point determination of a sample of compound X and find that it melts with a range of 119-129*C, which of the following WOULD NOT be the reason you see this result? Sample has a soluble impurity O Sample has air pockets Sample has an insoluble impurities Determination made too fast 5) Sources of error - you will need this section for every experiment Why some melting points may not have agreed with literature melting points . -moisture in the air (absorbed by the sample) .- contamination of the sample ..thermometer in Melt-Temp not calibrated .. only instance where melting point could be higher than expected. (could also be lower than expected like all other sources of error) . -Determination made too fast criteria for filling melting point capillaries not adhered to OO SUB X 00:19:33
