Question
Multiple true-false type questions.
State whether the following statements are true or false.
I. The principle of distillation is based on the difference in the solubilities of two components in the mixture.
II. Chromatography can also be used to detect contamination in food.
III. The particle of colloids can be separated by using the centrifugation method.
Hint:
Distillation is based on different boiling points.
The correct answer is:
The principle of distillation is based on the difference in the boiling points of its constituents.
Chromatography can also be used to detect contamination in food, in high performance liquid chromatography(HPLC).
The particle of colloids can be separated by using the centrifugation method.
