What is the correct position of the thermometer bulb in the simple distillation apparatus? Select one: 1 inch above the bottom of the flask. 1/2 inch above the liquid level. 1/2 inch below the side-arm of the distillation head. • At the bottom of the graduated cylinder. 1 inch below the liquid level. The thermometers use alcohol now, so placement is not an issue.

What are the applications of simple and fractional distillation A)Simple distillation is used when a substance is less than 10% impure while fractional distillation is used to purify a compound when the impurities are greater than 10% of the mixture. B) Simple distillation is preferred when a higher percent recovery of pure material is desired. C) Fractional distillation is preferred when a higher percent recovery of pure material is desired. D) Simple distillation must be done if the compound has...

A) A simple U-tube that is open at both ends is partially filled with a liquid of density 222 kg/m3. Water is then poured into one arm of the tube, forming a column 13 cm in height, as shown in the following diagram. The density of heavy liquid is 1000 kg/m3. What is the difference, h1, in the heights of the two liquid surfaces? Answer in units of cm. b) A simple U-tube that is open at both ends is...

The relative volatility, defined below, is often used as a simple way to relate the liquid and vapor compositions for a binary system. This worksheet examines the impact of relative volatility on the split between two components in a batch distillation process. An equimolar mixture of A and B is charged to a still. The mixture is distilled until 50% of A (the more volatile component) is vaporized a) Species A and B are present in a batch distillation still....
