1. You are given a substance that is equally soluble in water and hexane (two immiscible solvents). a) What is K,? b) If you start with 10 g of the substance dissolved in 100 ml of water and are given 100 ml of hexane to extract with, algebraically show that it is better to do two smaller extractions using 50 ml of hexane for each extraction than it is to do one extraction using 100 ml of hexane.

If a mixture is distilled rapidly, the separation of its compound is poorer than if the mixture is distilled slowly. Please explain why is that so using your own understanding. I don't need a copy-pasted answer from google.
- Suppose your sample is mixed with other stuff that is not soluble in your recrystallization solvent. Whenfiltering, should you rinse with hot solvent or cold? Why? - Suppose you've isolated crystals of your sample and are now filtering them. Should you rinse with hotsolvent or cold? Why?
B. Determining the Composition of a Mixture of Sodium Chloride and Sodium Nitrate Partner I Prepare a solution of sodium chloride + sodium nitrate and indicator. Obtain a dropper bottle of potassium chromate (indicator) solution. To a clean and dry 125 mL Erlenmeyer flask, add about 40 mL of water and 8 drops of indicator solution. Weigh out approximately 0.05 grams of sodium chloride + sodium nitrate solid and record its exact mass. Dissolve the solid in the solution from step 1, stirring with a stirring rod to ensure complete dissolution. Determine and record the total mass of the Erlenmeyer flask and solution, noting the balance that you use to weigh. Rather than measuring the volume of silver nitrate solution added as in Part A, we will measure the mass of titrant added and make use of the weight-percentage concentration of silver nitrate in calculations. Prepare the silver nitrate solution. Obtain about 15 mL of 1.70% w/w silver nitrate solution in a 50 mL beaker. Designate a…

CREATE A SCHEMATIC DIAGRAM FOR THIS PROCEDURE: C. Preparation and storage of standard solutions 1. Use the weighed and transferred NaCl powder in procedure B. Dissolve it in about 10 mL distilled water. Use a stirring rod to gently stir the solution until it has been dissolved to an extent. Make sure you will not incur any noise while stirring. 2. When the NaCl powder is partially dissolved, transfer the resulting solution into a 100 mL volumetric flask. Use a stirring rod and funnel. 3. Repeat steps 1 and 2 until no NaCl remains in the beaker and until you are almost at the mark of the volumetric flask. 4. Rinse the last portion of the solution from the stirring rod into the volumetric flask with a stream of water from the wash bottle. Rinse the funnel and remove it. Dilute the solution in the flask using a Pasteur pipette until the bottom of the meniscus is even with the graduation mark. 5. Put a stopper on the volumetric flask. Invert the glassware up and down around five…
Which of the following is true when preparing solutions? a. Make sure that the solvent and reagents are contaminated. b. When diluting to the mark using a volumetric flask, the upper meniscus and mark should be at eye level. c. If amount added is over the mark, you cannot just take out the excess liquid and preparation must be repeated. d. After mixing the contents of the flask and the level of the meniscus seems lower than the mark, add more diluent.

Construct an approximate boiling-point-composition diagram for a benzene– methanol system. The mixture shows azeotropic behavior (see Table 15.3). Include on the graph the boiling points of pure benzene and pure methanol and the boiling point of the azeotrope. Describe the behavior on distillation of a mixture that is initially rich in benzene (90%) and then for a mixture that is initially rich in methanol (90%).
