- How do you separate sodium hydroxide from the crude mixture?(extraction, reactive extraction, recrystallization). Write a few sentences for each technique explaining themThe method of extraction for Roman chamomile is: Choose one answer. a. cold-press extraction b. steam distillation c. water distillation d. solvent extraction
- Make a schematic diagram of the recrystallization procedure.If we are recrystallizing a PURE compound, what will happen to the sample if we cool the solution rapidly, i.e., placing it on an ice bath without cooling it first at room temperature? Note: kindly disregard the effect of rapid cooling on the container used.A. Test for Unsaturation To 3 drops of toluene add 3 to 4 drops of 1% potassium permanganate solution and shake. Give the results. B. Take 10 drops of toluene and add 2-3 drops of a solution of bromine in carbon tetrachloride until a faint color is obtained. Divide the solution into two separate vials. Expose one vial in sunlight, and keep inside your locker the other. Cover both vials. Compare their appearance after 10 minutes. Interpret the results. Give the equation. C. Demonstration (to be performed inside the hood) Take 2 test tubes and to each add 5 drops of liquid bromine. To one test tube, add a pinch of a halogen charrier (iron fillings). To both test tubes, add 3 drops of toluene. Expose a moist blue litmus paper to the fumes. Describe and interpret the results. Give the equation
