specific melting point‚ within one or two degrees Celsius. This is in opposition to a mixed‚ or contaminated substance‚ which will have a broad melting range. Therefore‚ when we mix our unknown with samples of phenacetin and acetanilide‚ whichever mixture has a more accurate melting point will tell us what our unknown is. It is also important to make sure that the resulting melting points are close to what the proven melting points of the substances are. The lab manual tells us that acetanilide should
