Describe how you can get two different values

Reference no: EM13268644

1) You melt and observe decolorization, but miss the melting point. Should you cool the sample and re-melt it, or start over?

2) You and your lab partner take melting points of the same sample. You observe a melting point of 101-107°C, while your partner observes a value of 110-112°C. Explain how you can get two different values with exactly the same sample.
