A unknow compound was found to have an experiment melting point , MPexp, of 126.0-130.2 degree Celsius.Assume the thermometer in the experiment was pre -calibrated to read accurate temperature.(a) .Comment on the purity of the unknow. Briefly explain. (b) . Achemist is given a list of possible identities for the solid unknown. which is the likely identity? Explain your decision. Compound melting point.
A 87.5-88.5 degree Celsius
B 125.5-127.0 degree Celsius
C 132.5-134.5 degree celsius
a) compound is almost pure as the melting point range i.e. from 126°C to 130.2°C is quite sharp , only small impurities could be there (a little only ) .
b). The unknown compound's melting point matches with option B possible identity (125.5 - 127°C ) and thus unknown compound is this possible identity probably. Option (B) is correct.
