[单选题]
A mixture is composed of wood chips, water, and sodium chloride. Which sequence of techniques could be used to isolate the wood chips and the sodium chloride separately?
A. Evaporation followed by paper chromatography
B. Filtration followed by paper chromatography
C. Evaporation followed by solvation
D. Filtration followed by evaporation
参考答案: D
本题详细解析:
To answer this question, the student must understand the properties of the mixture's components.
The wood chips would not dissolve in the water, so they are filtered out first. This will leave the sodium chloride dissolved in the water. The water can be evaporated to remove the water (to isolate the salt).
Paper chromatography would be ineffective in this scenario as it is used for separating substances such as dyes, pigments, and proteins.
This question is categorized as medium complexity because the student must understand the properties of matter and separation techniques.
