Experiment for pure and impure naphthalene?
It is easily checked by melting point of Naphthalene, if it is pure its melting point is 79 Celsius otherwise less than 79 Celsius.
Does impure and pure chemicals melt at the same temperature?
No. Every chemical has a different melting point, so the temperature varies.
Is pencil point pure or impure?
Pure

How do you distinguish a pure substance?
A pure substance will melt over a very narrowtemperature range.An impure substance will melt over a broader, lower temperature range.
How would you know whether a chemical is pure or impure?
An inpure chemical boil over a range of temperature. While, a pure solution melt at a fixed temperature.
Does impure and pure chemicals melt at the same temperature?
No. Every chemical has a different melting point, so the temperature varies.
