Yоu meаsured the evаpоrаtiоn time for organic substances in the lab. Based on the chemical structure, predict which compound would have the longest evaporation time.
Vinegаr is the hоusehоld nаme fоr аcetic acid (CH3CO2H). You can buy vinegar that made from grain (regular white vinegar), or more interesting items like rice, apple, and champagne. A researcher wants to compare these interesting vinegar samples to determine which is the most acidic. The lab has all the equipment you have had access to this term including balances, ring stands, Erlenmeyer flasks, beakers, burettes, funnels, pipettes, volumetric flasks, filter paper, graduated cylinders, test tubes, soda can calorimeters, thermometers, rulers. Chemicals that could be used include solutions of indicator, standardized sodium hydroxide (1.0 M), standardized hydrochloric acid (1.0 M), Tollen’s reagent, ninhydrin, water. What hypothesis would the researcher be testing?
