Kinetics Studies in a Washing Bottle

Abstract
The kinetics of the decomposition of hydrogen peroxide using iodide ion in aqueous solution is studied in sealed completely-filled washing bottles. Oxygen gas produced by the decomposition of the hydrogen peroxide forces liquid out of a bottom feeding washing bottle. After an initiation period of a few minutes at room temperature, the rate at which the liquid is expelled from the spout of the of the washing bottle stabilizes. A comparison of the rates for different reaction concentrations results in a rate law that is approximately first-order with respect to both hydrogen peroxide and iodide concentrations. Because the need for a gas buret to measure oxygen volumes is not necessary, the experiment can be conveniently performed by a student seated in a wheelchair.
