Answer the following questions following a Solubility and recrystalization lab for organic chemisty. 1. In a solubility and recrystallization lab you are working with the following chemicals : solids (benzoic acid, acetanilide,naphthalene, and resorcinol) and three solvents (water, ethanol and petroleumether) discuss and rank the polarity of the solvents and the polarity of the compounds being investigated. 2. Briefly describe how a mixture of sand and benzoic acid (soluble in hotwater) could be separated to produce pure benzoic acid.

Method Note: In steps 1 and 2 you will use the technique of weighing by difference to measure the exact mass of the sample of the ethylenediaminetetraacetic acid copper(II) disodium salt. This technique is described in the 'Techniques' section above and is available to watch as a chemistry skills video online (link available in Moodle). Weigh the ethylenediaminetetraacetic acid copper(II) disodium salt 1. If the sample tube on the balance is not already about one-third filled, fill it to about 1/3 of its height with ethylenediaminetetraacetic acid copper(II) disodium salt. Place a plastic spatula in the sample tube with the ethylenediaminetetraacetic acid copper(II) disodium salt and place on an analytical balance. Tare the balance so that it reads zero. Warning: After carrying out step 1, do not place the spatula on the bench, as this may result in a loss of sample, and hence an incorrect determination of the mass of the sample. 2. Using the spatula, transfer without loss (i.e. don't…
