It doesn't decolourize on heating and go to a temperature of 240

Paraffin oil is used in instruments as a lubricant due to its low viscosity and ability to reduce friction between moving parts. Although benzoic acid has a higher melting point compared to paraffin oil, it is not commonly used as a lubricant in instruments due to its acidic nature and potential reactivity with other materials.

Why we use paraffin for determination of melting point?
Liquid paraffin is used in thermostatic baths, to maintain a constant temperature.
What is the melting point of benzoic acid?
the melting/ freezing point is approximately 50°C
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 fifty percent 2-naphthol and fifty percent benzoic acid?
The melting point of a mixture of 50% 2-naphthol and 50% benzoic acid will depend on the exact proportion of each compound present and any potential interactions between them. However, the melting points of the individual compounds are approximately 122°C for 2-naphthol and 122-123°C for benzoic acid.
What is the flammable solid used to make candles?
Paraffin wax is a common flammable solid used to make candles. It is derived from petroleum and has a low melting point, making it ideal for candle-making.
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.

What are physical properties of benzoic acid?
Physical properties of benzoic acid:-density: 1,2659 g/cm3-melting point: 122,41 oC-boiling point: 249,2 oC-refractive index: 1,5397

What would happen to the melting point of pure benzoic acid if 2-naphthol was mixed in?
The melting point of pure benzoic acid would likely decrease if 2-naphthol was mixed in. This is because the presence of 2-naphthol can disrupt the crystal lattice structure of benzoic acid, making it easier for the molecules to move past each other and causing the melting point to decrease.
