TRUE OR FALSE, if false then give the correct word to make the statement true then explain 1. Sublimation occurs when a solid has a relatively high vapor pressure at a temperature [above] its melting point. 2. To isolate the desired chemical, a single extraction is [more efficient] than extracting the compound numerous times. 3. The compounds are separated in liquid-liquid extraction based on their relative solubilities in two [immiscible] liquids.
Give some advantages of steam distillation over simple distillation.
3.Why is it dangerous to perform distillation on a closed (airtight) system?
Procedures: 1. Take 4, 500 ml of conical flasks, number them as 1,2,3,4. 2. Weigh 50g of sand to each of the 4 conical flasks. 3. Accurately weigh 5g of pure Na2CO3 and put it in each conical flask. Now each conical flask has 50g of sand and 5g of Na2CO3, Mix well. 4. Add 15 ml of water to each conical flask to wet the solid. 5. Measure and pour 50 ml, 100 ml, 150 ml, and 200 ml of water into the conical flasks 1,2,3,4 respectively. From procedures above in leaching experiment, we are using sodium carbonate as a solvent. A. True B. False
Which among the variables is NOT part of the distillation process? Polarity Vapor Pressure Temperature Phase interaction

A 25 g organic substance was purified using recrystallization. Amount recovered after recrystallization was 18 g. Determine % purity of the sample (b) If % yield obtained after sublimation process was 60%, how much sample was present if 12 grams of an organic compound was recovered? (c) Determine % impurity from b
What are the differences between a simple distillation and steam distillation?
A lower and/or broader melting point range for a compound after recrystallization most likely results from ________. insoluble impurities such as dust or lint the material still being wet with the recrystallization solvent the compound decomposing in the heated solvent the compound undergoing a chemical reaction with the solvent
Some organic solvents do not work well in liquid-liquid aqueous extractions. Ethanol (HOCH2CH3) is a common inexpensive solvent, but is a poor solvent for extractions. In ten or fewer words, provide an explanation for why ethanol is a poor solvent selection for extraction. Hint: you may want to look up various properties of the molecule.
Write TRUE if the BOLD word/phrase makes the statement correct. Otherwise, write the correct WORD/PHRASE that will make the statement true. If there are two bold words/phrases in a number, write your answer for EACH of the bold words/phrases. 1. In the extraction of caffeine, NaOH was added to dry the collected organic layer. 2. Purification of caffeine via sublimation was possible because it has a high sublimation point at a temperature above its melting point. 3. The E/Z designation is used to describe the orientation of identical groups in alkenes.
