Accepted Answer

∻Solution∻ ‖ 1 ⋮ **Identify the appropriate separation technique**: To separate two miscible liquids with different boiling points, distillation is the most suitable technique. ‖ ‖ 2 ⋮ **Justify the technique**: Distillation works by heating the mixture until one of the components boils and vaporizes. This vapor is then condensed back into a liquid in a separate container. Since butanol and pentanol have different boiling points, as indicated in the table (117.7 °C for butanol and 131.6 °C for pentanol), they can be separated by carefully controlling the temperature. ‖ ∻Answer∻ ⚹ The student could use distillation to separate the mixture of butanol and pentanol. By heating the mixture to a temperature between the two boiling points, the butanol will vaporize first and can be condensed and collected, leaving the pentanol behind. ⚹ ∻Key Concept∻ ⚹ Distillation ⚹ ∻Explanation∻ ⚹ Distillation is a technique used to separate components of a mixture based on differences in boiling points. It is effective for separating miscible liquids like butanol and pentanol. ⚹◊What type of separation technique could the student use to separate butanol and pentanol from each other based on their physical properties?⍭ Generate me a similar question◊
