An analysis of the breakdown of hydrogen peroxide experiment
Add a few drops of the hydrogen peroxide solution. This may have resulted due to a number of reasons. On the other hand, more diluted hydrogen peroxide reacted slowly and the oxygen bubbles were released sporadically.
Loosely connect the bung into the conical flask and make sure the delivery tube connects to the inverted measuring cylinder.
Prediction: I predict that the higher the amount of Hydrogen Peroxide I use then the faster the displacement reaction will be.
Catalase and hydrogen peroxide experiment
I then divided the initial rate laws for Parts I and II, which canceled out the hydrogen peroxide as the concentration of hydrogen peroxide did not change in these parts. I think this because the higher the concentration, the more atoms there are, then there are more chickens and therefore there are more collisions as a direct result of the concentration Test tube 3 Add a couple drops of sodium thiosulfate solution and observe. This works because the decomposition of H2O2 creates oxygen gas, which would increase the pressure in the test tube over time. Place about 5 ml of the KI solution in a test tube. Prediction: I predict that the higher the amount of Hydrogen Peroxide I use then the faster the displacement reaction will be. An accumulation of hydrogen peroxide can be deadly, so it has to be decomposed.
The faster the reaction is, the faster the pressure will increase. Practical Investigate the effects of various catalysts on the decomposition of hydrogen peroxide.
To estimate a pseudo rate coefficient with respect to iodide. Clean the apparatus as directed by your teacher.
