Why we use paraffin for determination of melting point?
Liquid paraffin is used in thermostatic baths, to maintain a constant temperature.
In the experiment of determining melting point why each time fresh paraffin liquid should be taken?
Paraffin oil is nontoxic, noncorrosive and stable.
What is the melting point of benzoic acid?
the melting/ freezing point is approximately 50°C
What is the Paraffin Wax freezing Point?
The freezing point is the same as the melting point; it is the point at which the paraffin transitions from solid to liquid. 37 °C (99 °F)
What is the boiling point of liquid paraffin?
Paraffin is a class of hydrocarbons called Alkane the most basic alkane being methane. Methane has a boiling point of -161 degree Celsius. As it goes higher the bp increases as the energy required to break the hydrogen bonding increases.
Why does benzoic acid has high melting point?
122.4 °C
Why benzoic acid unmelt even 200 Celsius?
Benzoic Acid has a melting point of 122oC. If your sample did not melt even at 200oC, then you can only assume that the sample in Whole or Part was not Benzoic Acid. It must have been contaminated with some other compound with a much higher melting point.
