GRAVIMETRIC DETERMINATION OF SULFATE Purpose You will be given a solid powder‚ which has been dried to constant mass. The sample is water soluble. The purpose of this experiment is to determine the concentration of sulfate in your solid sample using gravimetric analysis. Background Gravimetric Analysis The goal of most quantitative chemical analysis measurements is to estimate the relative abundance of an analyte in a chemical sample. For solid and liquid samples‚ a very common expression

Determining the Enthalpy of a Chemical Reaction All chemical reactions involve an exchange of heat energy; therefore‚ it is tempting to plan to follow a reaction by measuring the enthalpy change (∆H). However‚ it is often not possible to directly measure the heat energy change of the reactants and products (the system). We can measure the heat change that occurs in the surroundings by monitoring temperature changes. If we conduct a reaction between two substances in aqueous solution‚ then the

From the graph I can clearly see that Distilled water has a much larger concentration of water then the cell sap in the potato tissue. I can make this conclusion because the results show a big increase in weight of the potato piece. Meaning that water has moved from outside the potato into the potato due to Osmosis‚ proving that the distilled water had a higher concentration of water‚ as water moves from a high concentration to a low concentration. I can also see that the glucose

Determination of Chemical Formulae: The Reaction of Zinc and Iodine By Sarah Abstract: The main objective of this experiment was to use to the reaction between zinc and iodine to examine the validity of the Law of Conservation of Mass and the Law of Constant Composition. The Law of Constant Composition was tested by determining the mass of each of the reactants‚ zinc and iodine‚ and comparing their total to the mass of the zinc iodide product plus the excess zinc. The total mass of the reactants
