    Chemical Separation Introduction: The objective of this experiment was to extract the pigments from spinach leaves‚ perform Thin Layer Chromatography (TLC) on the spinach leaf extract‚ and then determine the best solvent mixture to use to separate the pigments in the extract. The pigments are located inside the chloroplast walls in the cells of the spinach leaves. In order to obtain the pigments the cell walls must be broken down thus exposing the pigment containing chloroplasts. Upon

    Stephany Matos Chem Lab: Chemical Equilibrium Lab 52 Synopsis Iron (III) ions react with thiocyanate ions (SCN-) to form iron (III) thiocyanate‚ FeSCN2+. It is represented in the equation below: Fe3+ (aq) + SCN- (aq) FeSCN2+ (aq) Therefor the equilibrium constant for this reaction is: KC = [FeSCN2+]/([Fe3+]•[SCN-] For this experiment we were able to determine the equilibrium constant KC for this reaction. First we prepared five different mixtures with known initial concentrations of

    Abstract: The objective of Experiment 1 was to observe some chemical changes. While observing the chemical changes in elements I also experimented with household cleaners to see how much chemical properties relate to our daily lives. Chemical changes occur all around me and I go without noticing them all the time without a second thought. This experiment opens my eyes to different chemical reactions occurring around me. This experiment also shows the importance of dilution. If I did not dilute something

    Lillian Zhang AP Chemistry 3rd Period Formula of an Unknown Hydrate The purpose of the Formula of an Unknown Hydrate lab is to determine the weight percentage of H2O hydrated to an unknown salt and the empirical formula for the hydrated salt. To do this‚ a massed amount of the hydrate is heated over either a hot plate or Bunsen burner. This causes the water to be removed‚ leaving the anhydrous salt behind in the dish. The mass of the anhydrous salt‚ now with the absence of water‚ is less than
