MEASURING pH Date of Lab: 02/09/13 Date Report submitted: 02/26/13 Purpose of the experiment By doing this experiment‚ we were trying to learn how to measure a pH with a pH meter to determine whether a solution is weakly‚ moderately or strongly acidic or basic; but also to compare the different data founded to see how the addition of certain liquid to a solution may affect the pH of the initial solution. Materials We used: * Tap water‚ distilled water‚ Soda and milk as the main

POTATO INTO BATTERY Abstract a.Purpose To lessen the consume of electric charge b. Procedure We insert copper and zinc electrodes in to the potato‚ close but not touching each other. We use Clip leads to connect our electrodes to the Multimeter to measure voltage between two electrodes or current passing through the multimeter. For this experiment we used a galvanized nail for our Zinc electrode. c. Result It did go well and the potato did give voltage to the equipment (clock) However‚ the

Determining the Production of Glucose During Changes in Temperature and pH‚ and Manipulation of Specificity and Cofactors BIOL-1406-SL8 November 16‚ 2012 Abstract Enzymes are biological catalysts. They work by lowering the activation energy needed to initiate a chemical reaction. Enzymes work within an optimal temperature and optimal pH. Enzymes are highly specific for a single substrate. The Enzyme is usually much larger in size than the substrate it binds to. In some cases‚ an enzyme requires

LAB ACTIVITY: Coastal and Continental Temperature Ranges ANALYSIS: 1) I can tell from the temperature curves that the cities are all in the Northern Hemisphere because it ranges from low to high then back to low again starting in January. 2) The city that has the greatest yearly temperature range is Bismarck‚ N.D. 3) The cause of the greatest range is because the location is located most near the pole. 4) The rates of heating and cooling do not differ much for New York

On the income side‚ nonincome charges—depreciation and indirect business taxes—are covered in detail because these usually give students the most trouble. Other measures of economic activity are defined and discussed‚ with special emphasis on using price indexes. The purpose and procedure of deflating and inflating nominal GDP are carefully explained and illustrated. Finally‚ the shortcomings of current GDP measurement techniques are

Grade 12 Biology (SBI 4U1) Nicole Mikulis Unit: Biochemistry Sept 14 2012 Lab: Effect of temperature and pH on catalase activity BACKGROUND Catalase is an enzyme that detoxifies chemicals that might harm the cell such as hydrogen peroxide (H2O2). The enzyme breaks H2O2 into water and oxygen. The production of the oxygen gas bubbles serves as evidence that the catalase enzyme is working. As catalase is breaking the bonds between H2O2‚ it is releasing energy in

Lab Report: Purpose: The Objective of this lab was to learn how to measure the pH (or acidity) of commonly known fluids‚ using the correct tools and procedures. To then use that data to document the changes noticed when mixing those same fluids and changing their respective pH levels. Materials: In order to conduct this experiment several pieces of equipment and other materials were needed. The first item was a graduated cylinder‚ which was used in order to measure out the precise

This scene is broken into 4 sections‚ within it there are 3 characters; Donna‚ Rodney and Melissa-Anne. The first section of the scene was solely Donna explaining what was going on and the current situation of the party. The next section starred Melissa-Anne and Rodney; this was when they were waiting for Donna to pick them up‚ they were in Rodney’s bedroom. The following section was again of Donna and she was explaining to the audience that she had realized what was actually going on and also she
