An investigation of how concentration affects rate of reaction between catalase and hydrogen peroxide AIM To find out how rate of reaction between catalase and hydrogen peroxide is affected by concentration of hydrogen peroxide. Hydrogen Peroxide---------------------->Water + Oxygen 2H2O2------------------->2H2O+O2 VARIABLES Independent - concentration of hydrogen peroxide. Dependant - amount of oxygen collected in a gas syringe or upturned measuring cylinder. Controlled variables - temperature, pressure, enzymes, and homogenisation, volume and concentration of catalase. Light does affect some reactions, but in this case the reaction is not affected and so we do not need to worry about light levels. We need to make this a fair test and so we must pay attention to the controlled variables. Pressure is not a problem, as all experiments will be conducted indoors in a lab. The hydrogen peroxide is the regulated factor, as it is the concentration of this that we are controlling. After the acid has been poured in and the bung applied,...
