The Potato Blight

Now I will tell you something about the big famine through the potato blight. Ireland has been ruled by the British government since 1542 (fifteen forty-two ) . The british great land owners owned the total ground of Ireland. In former times, the potato was easy, fast and cheap to cultivate. Besides, the potato was…

The first one is surface area

Factors affecting Osmosis in Potato Tissue Background Scientific Information: Key Variables: There are several variables we must consider. These are: 1. Length of potato chip 2. Mass of potato chips 3. Temperature 4. Variety of potato 5. Volume of salt solution 6. Duration 1. We must keep the length of potato chip the same because…

The activity of potato catalase

The independent variable in this experiment will be the buffer solutions. A buffer solution is used to maintain the pH level throughout the reaction to ensure a fair test. In this experiment, the pHs of the buffer solutions will be varied, as shown in the concentrations table above. Experiment Procedure: 1) Utilising a cork borer,…

Influence of pH on the activity of Potato catalase

Therefore SA = 7. 065mmi??. So, 7. 065mmi?? x 50mm will provide the volume of the 5cmi?? space in the manometer tube, which is 353. 25mmi??. The rate of reaction can now be calculated as: Rate of Reaction = Volume Time The results for the rate of reaction are displayed as follows: pH Average Time/Seconds…

Effects of Osmosis on Living Tissue

What is the effect of osmosis on a slice of potato in varying salt solutions? Six different concentrations of salt water (0%, 0,4%, 0,8%, 1,2%, 1,6% and 2,0%) will be used in order to observe how the inserted potato slice changes. The length of the potato slice will be measured before and after leaving it…

Catalase’s Reaction with Hydrogen Peroxide When pH Level is ChangedAll living organisms contain catalysts. These catalysts are used to speed up reactions and processes in all organisms. Enzymes are responsible for enabling chemical reactions that occur in all living things. In this experiment the enzyme catalase (found in potatoes) and hydrogen peroxide cause chemical reactions…
