The enzymatic Decomposition of Hydrogen peroxide

Naoto OKAWA

Aim:

To investigate one factor affecting the rate of enzymatic decomposition of hydrogen peroxide by catalase.

Hypothesis:

Bigger the volume of the catalase, faster the rate of reaction

Safety:

Due to the hydrogen peroxide is corrosive we need the protection for example glasses and gloves Safety Precautions. Avoid any contact with hydrogen peroxide it will burn our skin. If any contact with hydrogen peroxide, wash the part where get contact painstakingly with water and report to teacher.

Variables:

Independent Variable – Volume of the potato

Cut the potato into different sizes, dimensions of the potato pieces were equal

Dependent Variable - Time taken

Fill the test tube with a little bit of hydrogen peroxide. Take the time when potato is placed inside hydrogen peroxide. Stop the stopwatch when the babbles are came off up to the top of test tube.

Method:

Procedures-

1. Wear the goggles and gloves

2. Carefully make the potato to pieces by using mold make 5 of it

3. Measure the dimensions of the potato pieces with the ruler

4. Measure 5ml of hydrogen peroxide with the measuring cylinder

5. Pour 5ml of hydrogen peroxide into the test tube

6. Release one piece of potato into the test tube

7. Start the stopwatch as ...
