1.0 Introduction 1.1 Aim and Assumptions: The aim of this experiment is to observe the rate of diffusion of diethyl ether vapour into stagnant air‚ and then determine the diffusivity. An error analysis of this calculation also had to be carried out. The following assumptions made were: * Diethyl Ether is an ideal gas * Partial pressure at the top of the tube was equal to zero * Mass transfer resistance between the liquid surface at the bottom of the tube is insufficient‚ compared with the

Osmosis in Potato Tissue Experiment Background Information Osmosis can be defined as the movement of water across a semi-permeable membrane from a region of high water concentration to a region of low water concentration. The semi-permeable membrane allows small particles through it but does not allow large particles such as sodium chloride. Osmosis will continue until a state of equilibrium is reached i.e. there is no area with a higher or lower concentration than another area

In the humus lab were were trying to find out if hydrogen peroxide would cause a reaction and show us the amount of humus in the soil by putting gas into a graduated cylinder with water to make the water level lower therefore showing us how much humus the material being tested contained. It showed that the sand was lacking humus but the mushroom compost was the most rich in humus. My hypothesis was correct because I predicted that the mushroom compost would produce the greatest amount of humus out

Abstracts Innovate a machine which is easy to use and that cannot tolerate with their accuracy‚ without affecting the prize of the machine. All over the world the resources of energy are reduced for that we can find new sources of energy. For that machine is both manually and power operated. In India‚ there is many industries which are engaged in production of manually pipe bending machine. Presently the pipe bending machine is power and manually both operated. But‚ the manually operated

onto the balance. The result is rounded to two decimal places. The graduated cylinder is used for measuring volume of a liquid or water displaced by a solid. The students look at lines‚ at eye level‚ drawn onto the side of the cylinder to measure the liquid level‚ significant figures depends on how accurate the marks go. Pipettes suck up or expel liquids. Students use the pipette to move liquids to a graduated cylinder by squeezing the top of the pipette to cause suction. Procedures: Students

An Investigation Into The Effect Of PH On The Activity Of Potato Tissue Catalase Aim The aim of my investigation is to see how pH affects the activity of potato tissue catalase‚ during the decomposition of hydrogen peroxide to produce water and oxygen. Catalase + 2H2O2 Catalase + 2H2O +O2 Catalase + Hydrogen Peroxide Catalase + Water + Oxygen Independent Variable The independent variable in this investigation is pH. Each individual enzyme has it’s own pH characteristic

Test the distilled water and tap water for the pH level to see if it were neutral so it wouldn’t make a difference to the results. 2. Set up 3 petri dishes and 3 measuring cylinders 3. Measure 10mls of tap water. Add water to the petri dish and add 5cm of Sensodyne (toothpaste) into
