Biology Coursework Title: How varying the concentration of Hydrogen Peroxide changes the rate at which an alginate bead reacts in Calcium Chloride. Equations: In this experiment I am investigating the reaction: 2H2O2 2H2O + O2 Hydrogen Peroxide Water + Oxygen Aim: I am going to try and find out how varying the concentration of Hydrogen peroxide changes the time it takes for the yeast alginate ball to rise from the bottom of the test tube with different concentrations of Calcium Carbonate and Water. Normally the decomposition of hydrogen peroxide takes a long time, but the catalyse will speed up the reaction. Introduction: Catalyse breaks down the Hydrogen Peroxide into water and Oxygen. We are measuring the production of Oxygen because it is a visible reaction, whist Hydrogen and Water are both clear fluids, so it would be impossible to see the actual reaction occurring. During the production of Oxygen, Oxygen sticks to the beads and cause them to...
