Part 1 To test how the temperature of water (cold, warm, and
hot) affects the rate of reaction at which an Alka Seltzer tablet dissolves.
Part 2: Effect of Concentration To test how the concentration of HCl (0.1M, 1.0M, 2.0M) affects the rate at which a piece of zinc metal will dissolve.
Part 3: Effect of Surface Area To test how the surface area of Alka Seltzer tablets (whole, chunks, crushed) dissolving in water affects the rate at which the tablet will completely dissolve.
Part 4: Effect of the Presence of a Catalyst To test how the presence of a catalyst can affect the rate at which hydrogen peroxide decomposes.
