Steam distillation is used to__________________?
Correct answer: B. Avoid thermal decomposition of a component
- A. Reduce the number of plates
- B. Avoid thermal decomposition of a component
- C. Increase the efficiency of separation
- D. Increase the total pressure of distillation
Explanation
Steam distillation lowers the boiling temperature by combining vapour pressures, allowing heat-sensitive substances to distil below their normal boiling points. This prevents or minimises thermal decomposition, whereas reducing plates or increasing pressure are not its purpose.
