Experiment 8: Hydrogen Phosphate Buffer Systems Purpose The purpose of the lab was to create a buffer solution and observe the capacity of the phosphate buffer system. Also‚ the experiment was meant to provide experience with the calculations and mathematics involved in creating the buffer solution. Finally‚ the lab was designed to provide an insight and appreciation for the necessity and complexity of buffers in our physiology and in the environment. Procedure No deviations were made from

Sofia Dominguez 10-O 19/03/14 Effect of pH on germination of seeds: Design Practical Introduction: The term pH stands for Hydrogen Potential it is used to determine the acidity of a substance. The pH scale goes from 0 to 14. The values that are smaller than 7 indicate the range of acidity. Higher pH values are alkaline and a pH of 7 is neutral. Acidity is a function of the concentration of hydrogen ions (H+)‚ or protons. The strength of alkaline solutions is measured by the concentration of hydroxide

Free Digestion
The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract (GI tract). The alimentary canal is made up of the oral cavity‚ pharynx‚ esophagus‚ stomach‚ small intestines‚ and large intestines. In addition to the alimentary canal‚ there are several important accessory organs that help your body to digest food but do not
