3. Take another 10mL of the temporary hard water and boil for 5 minutes. Filter, then add 5 mL of soap solution to the filtrate and shake. What is the result? Is the water hard? Why is this type of harness called "temporary hardness"? What other substances cause temporary hardness? Write the equation for removal of temporary hardness by heating. Give 3 other methods of removing temporary hardness in water.
Suppose you have a soil that is made up of 10% organic matter with CEC = 200 cmol/kg, 40% kaolinitewith CEC = 10 cmol/kg, and 50% vermiculite with CEC = 100 cmol/kg.1- Calculate the overall CEC of the soil by taking a weighted average of the three soil components.2- What percentage of the overall CEC is contributed by the organic matter? How does that numbercompare to the 10% of the soil itself that is organic?
Which of the following error will make the reported percent yield of Srli0a)2 too high? 1, Because of the porosity of the filter paper, some of the SrINO3)2 precipitate passes through the filter paper. IL. The drying oven, although thought (and assumed) to be set at 125°C, had an inside temperature of 54C III. Product is leaving in the oven (125°C) for 20 min instead of 10 min before measuring. All three I only only Om only None of the three In the Chemistry of Copper expeiment, starting mass of copper is 0.020g. If the percent recovery is 95%, what is the mass of Cu metal obtained at the end of the experiment? QUESTION 14 95.00 g O 0,950 8 O0.198 0.020 O 0.0198
Which of the following statements is true when considering temperature during a recrystallization? More than one answer may be correct. Using ice to cool the sample will speed up the crystallization process so that large crystals will be formed. It is important that the sample is dissolved in just enough hot solvent. O Ideally the hot solvent used will keep the impurities dissolved OR not dissolve them at all. Enough cold solvent should be added to dissolve the sample BEFORE heating it past its boiling point.

Suppose you have an organic sample X that is somewhat soluble in water, even though it issomewhat more soluble in dichloromethane or ether solvents. But if you do a singleextraction, you get only 60% of your material to transfer from the water to the organic layer.How many “washes” would it take to extract over 90% of your organic material extracted fromthe water layer?
Saponification of Wintergreen Oil The purpose of this experiment was to convert wintergreen oil into salicylic acid using an aqueous base while also learning how to hydrolyze esters under basic conditions, reflux a reaction, and perform a vacuum filtration. Practise Question 1. Based on the data determine the yield and melting point.
Please answer all 5 questions (it could be short answers). 5-1. What is the main barrier to separating liquid mixtures of less than 500 mL by distillation? 5-2. A sample mixture of ethyl benzoate (bp 212 Celsius) and dodecane (bp 216.2 Celsius) is injected on two GC columns. Column A has DC710 silicone oil as the stationary phase, and column B uses polyethylene glycol as the stationary phase. Which substance would be certain to elute first from column A and would the same material be expected to elute first from column B? Which column, A or B, would be expected to give the better separation of these two substances? 5-3. Question 5-2 refers to separating a mixture of two high boiling liquids by gas chromatography. These materials have similar boiling points. List several GC variables and conditions that would make it easier to separate thesesubstances by gas chromatography 5-4. Capillary GC columns have better resolution than packed columns even though the enormous surface area…

Extraction of Caffeine Post-lab 8. Ethanol is miscible with water. (After all, alcoholic beverages don t separate into an “alcohol‟layer” and a “water layer.”) Assuming that caffeine is soluble in ethanol, could you useethanol as a solvent to extract caffeine from coffee (rather than using dichloromethane asthe extraction solvent)? Explain why or why not. 9. A 12 oz can of Coke contains 46 mg of caffeine. One fluid ounce is equivalent to 29.57 mL(1 oz = 29.57 mL). What is the concentration of caffeine in Coke, in units of mg/mL? Showyour work. 10. What is an alkaloid?
Extraction of Caffeine Post-lab 1. What group of organic compounds does caffeine belong to? 2. Draw the structure of caffeine as a line formula. Redraw the structure of caffeine,showing all carbon and hydrogen atoms. 3. What is the molecular formula for caffeine? Use the molecular formula of caffeine tocalculate its molecular weight. 4. What does it mean for two solvents to be immiscible? 5. On the report sheet, you calculated your percent recovery of caffeine. a. If your percent was less than 90%, give at least one reason why it was less. b. A group of students have their percent yield more than 100%, give at least one reasonwhy it was more than 100%. Do NOT simply say “human error.” Be specific about the typesof errors (human or otherwise) that may have occurred, leading to a recovery more than eorequal to 100% (Is this possible Why?) 6. Based on what you observed during this experiment, is dichloromethane denser OR lessdense than water? Explain your reasoning. 7. Based on what…
