In a test tube, dissolve 10 drops of methanol in 3 ml. of water. Oxidize a copper wire spiral by passing it through a Bunsen burner. Plunge the red-hot wire into the alcohol solution several times, cooling the solution under the tap (faucet) so as not to evaporate too much of it. Next, add 1 drop of 0.5% resorcinol solution. Measure 2 ml. of concentrated sulfuric acid (CAUTION!) and pour this carefully down the sides of the test tube containing the mixture. Note the color of the zone intermediate between the acid and the solution. RESULT:
2. When performing the recrystallization of an impure solid, why is it advised to use the minimal amount of solvent possible? Group of answer choices To minimize the amount of pure solid lost due to its solubility. To minimize the cost of the recrystallization. To reduce the time needed to filter the pure solid from the solvent after recrystallization. To minimize the amount of hazardous materials used.

: Determine the lime and soda ash dose, in mg/L as CaO and Na2CO3, to soften the following water to a final hardness of 80.00 mg/L as CaCO3. The ion concentrations reported below are all as CaCO3. Assume lime is 94 percent pure and soda ash is 93 percent pure. Ca2+ = 155.0; Mg2+ = 62.0; HCO3- = 136.0; CO2 = 12.0
2. Questions: 1. CHM-202 Lab 2 Freezing Point Depression Rev2 G6-2022 10/14 From your understanding of colligative properties, how would you design an experiment to measure the freezing point of a material which freezes at -2 °C using the same apparatus used in this laboratory and any chemical reagents commonly found in a chemical laboratory. Ice is the only material you have available to cool the solutions. If you measured the boiling point of the solution used in Trial 4, would you predict it would have a boiling point equal to, higher than, or lower than the boiling point of pure cyclohexane? Explain your answer.
