Effects of Different Concentration of Catalyse on Hydrogen Peroxide
Aim: In this investigation I will try to find how long it takes for the filter paper disc to rise up whilst varying the amounts of concentration of catalyse.
Prediction: I predict that the lower the concentration of catalyse the longer it will take for the filter paper disc to rise to the surface of the tube.
Equipment:
- Hydrogen peroxide in a container
- Flat bottom tube
- Tweezers
- Filter paper discs
- Hole puncher
- Pipette
- Watch Glass
- Stop Clock
- Table of results
- Catalyse – 6.25%, 12.5%, 25%, 50%, 100%
Method:
- Firstly, we hole punched 15 holes using the filter paper.
- Next, we filled the tube half way with 100% hydrogen peroxide.
- Then we dipped the discs of filter paper into the catalyse which was in a watch glass.
- After that, we picked the discs from the catalyse using a pair of tweezers and soaked it with catalyse and placed it at the bottom of the tube which was filled with hydrogen peroxide.
- Next we timed how long it took for the discs to rise to the surface of the tube with a stop watch.
- To make it a fair test we repeated it three times with the same amount of concentration of catalyses.
- Finally, we put the results down on a table.
