Melting Point Determination Quiz

Which of the following is NOT required for determining the melting point of napoline?

• Bunson burner

• Microscope

• Capillary tube

• Liquid paraffin

What is the first step in preparing the capillary tube for the melting point experiment?

• Heating the paraffin bath

• Attaching the capillary tube to the thermometer

• Sealing one end of the capillary tube

• Filling the capillary tube with napoline

How much powdered napoline should be filled into the capillary tube?

• 4 to 5 mm

• 3 to 4 mm

• 2 to 3 mm

• 1 to 2 mm

Why is it important to stir the paraffin bath gently during the experiment?

• To ensure the temperature remains uniform

• To prevent the napoline from sticking to the tube

• To speed up the melting process

• To cool down the paraffin bath

What does the average of the two recorded temperatures represent in this experiment?

• The melting point of napoline

• The freezing point of napoline

• The sublimation point of napoline

• The boiling point of napoline
