    Irresistible? By Elizabeth Potter December 5‚ 2012 Lab Section 503 Abstract The over all goal of the Irresistible lab was to verify a buffer’s ability to resist changes in pH with consecutive 1mL additions of either a strong acid (HCl) or base (NaOH). The experiment entailed preparing a combination 10 buffered and non-buffered solutions and then monitoring the pH changes as a strong acid or base was added to the solution. By performing this experiment‚ it was found that with increasing amounts

    Formula of a Hydrate Lab Wednesday October 29‚ 2014 Chemistry Honors Purpose This lab was done to determine the percentage of water in a hydrate‚ which was CuSO4 ?H20. Not only the percentage of water can be found‚ the moles of water can be found per one mole of anhydrous salt. An anhydrous salt is a hydrate that lost its water. Using various lab equipment such as burners‚ crucible‚ and balance‚ and techniques such as the mass-to-mole ratio and mass to percentage‚ the percentage of water in a hydrate

    The lab “Aluminum Atoms” was designed to determine whether heavy-duty or house hold aluminum foil was the thicker than the other and to show the different atomic calculations of each type of foil. It was learned that heavy-duty foil is thicker than the household aluminum foil. An atom is the basic unit of a chemical element. Avogardo’s number‚ 6.02 x 1023‚ is the number of particles found in one mole of a substance. The molar mass is the weight of one mole (or 6.02 x 1023 molecules) of any chemical
