In this experiment we are going to observe how the rate of reaction varies when we increase the amount of Catalyst (Manganese Dioxide). This is the reaction: Word Equation: Symbol Equation:> Clamp> Gas syringe (100cm3)> Conical Flask (100cm3)> Stopwatch> Manganese Dioxide> Hydrogen Peroxide (5M)> Balance (measuring to 2d.p.)> Measuring Cylinder (100cm3)> Retort Stand> Boss As Hydrogen peroxide is corrosive care had to be taken while handling it. Safety goggles and Lab Coats were worn to protect our eyes and clothes form the Chemical. Also, the Catalyst, Manganese Dioxide is an irritant so care was taken when handling it as it could cause blisters by irritating the skin. A piece of paper was put on some scales measuring in grams to 2d.p. We tared the scales and placed the required amount of Manganese Dioxide on the paper. Then the catalyst that was taken on...
