During this experiment the change in pH of Citric acids is measured from start to equilibrium in mL. This experiment was tested by titration it had two separate trials. Through observations it was shown that the more concentrated acids needed more drops of NaOH to reach its equilibrium then the less concentrated acids. Introduction Sodium Hydroxide (NaOH) is a strong base and when it is titrated with a strong acid the equivalence point will be expected to be a pH of 7 (wyzant.com‚ Feb. 12). NaOH

Purpose: The purpose of this lab was to test how objects slightly acidic or slightly basic will affect the way catalase‚ the enzyme tested‚ denatures‚ or breaks down. Hypothesis: If the potato is acidic‚ it will react with the H2O2 more than it will with the raw‚ plain potato because the acid will denature the enzyme faster. The manipulated/independent variable is the raw‚ plain potato while the responding/dependent variable is the other types of potatoes used in the experiment. Materials:

Observing osmosis‚ plasmoylsis and turgor in plant cells Investigation * Get a single layer of plant cells. If you are using red onion‚ cut a 1 cm square from a fleshy piece of onion and then peel off a single layer of the red cells. If you are using rhubarb‚ peel a piece from the epidermis. If you are using toadflax peel a piece of the lower epidermis of a leaf. * Place the strip on a slide and cover it with a drop or two of distilled water. Add a cover slip. * Look at the cells through

Diffusion and Osmosis of Solutes and Water Across a Membrane Brittany Bacallao Nova Southeastern University Abstract: This experiment gave a visual understanding of osmosis and diffusion. The first experiment proved that solutes would move down a concentration gradient if permeable to the selective membrane. The second experiment proved different solute concentrations affect the movement of water‚ depending on the solute concentration inside the cell. The purpose of this lab was to look for

Practical 1- An experiment to observe the features of an Onion Cells Method: Gather all equipment that will be used for the experiment and check that they are clean and undamaged. Using forceps‚ peel the membrane from the underside of a small piece of onion. Place the membrane flat on a clean‚ glass slide and add one drop of iodine solution. Use a pin to carefully lower the cover slip over the slide‚ ensure there are no air bubbles before the use of the slide. Set the microscope to its lowest

Finding the Optimal pH of the Enzyme Peroxidase with the Aid of a Spectrophotometer ABSTRACT The peroxidase enzyme was partially purified‚ and the enzyme activity was calculated with the use of a spectrophotometer‚ demonstrating the effect of pH on peroxidase activity. The objective of this exercise was to determine the ideal pH for peroxidase activity. The data concluded that the optimum pH for peroxidase activity is 5‚ and the “standardized” enzyme volume is 2.8mL
