4. Often we will ask that you scale your procedure up or down, meaning we will change the amounts of material we will use. The following is a procedure as written in an organic lab experiment. Write the procedure out as if you were asked to scale up by a factor of 2. Make any necessary changes to equipment sizes, reaction times, etc. Remember that you should never heat a reaction vessel that is more than ½ full. "In a 50 mL round-bottom flask place 2 grams of compound X and 15 mL of benzene. Reflux the reaction for 30 minutes. After the reaction has cooled, add 10 mL of ice-cold water. Collect the product by vacuum filtration and wash it with two 10 mL portions of ice-cold water."
