Experiment 4: Analyze a solution of potassium hydroxide using standard hydrochloric acid Theory . Introduction: Titration is a procedure used in chemistry in order to determines the molarity of an acid or a base. In the other words‚ it is also consider as acid-base neutralization reaction (Darrell D. Ebbing 1976). A chemical reaction is set up between a know volume of a solution of unknown concentration and a known volume of a solution with a known concentration. The relative acidity or

Concentration ·Enzyme Concentration The factor I am changing is surface area of potato containing Catalase. By increasing the surface area of the potato‚ you make more Catalase molecules be exposed to hydrogen peroxide. This will result in the rate of reaction increasing because it increases the chance of more successful collisions between the enzyme and the substrate. Catalase is an enzyme found in food such as‚ potato. It is used to break down a poisonous by-product of metabolism called hydrogen

Determining the Rate of Osmosis through a Semi-Permeable Membrane Schneider‚ Justin* Sec 16 and Thomas Hudson Introduction Water is the principle solvent in cells. There are three conditions that a cell may be subjected to in the cells physical environment. The cells may be isotonic‚ hypotonic‚ and hypertonic. Isotonic is when the cell and is environment have equal concentrations of solutes. Therefore cells in an isotonic solution do not experience osmosis. When the cell is hypotonic it

The 1845 Great Irish Potato Famine negatively affected Ireland and its people. Due to this famine‚ many factors resulted from it and changed the course of Irish history. Three of these factors are reduced population‚ decline of the Gaelic language‚ and increased harshness of the Irish landlords. The Great Potato Famine was caused by a type of fungus called potato blight‚ which caused the potatoes to become mushy and inedible (Trueman). The 1846 potato crop was a failure due to this fungus

Diffusion and Osmosis Experiment with a Shell-Less Egg After Three days of Testing Methods with Water and Corn Syrup Lisa July 1‚ 2013 Purpose To use the properties of diffusion and osmosis to see the effects of either corn syrup or water on a shell-less raw egg over a three day period. While looking to see the effects of these liquids on the raw egg‚ one can also apply the properties of hypotonic‚ hypertonic‚ and isotonic solutions. Introduction Cells have an outer covering called the cell membrane

PROPERTIES OF SOLUTIONS A solution is a mixture of materials‚ one of which is usually a fluid. A fluid is a material that flows‚ such as a liquid or a gas. The fluid of a solution is usually the solvent. The material other than the solvent is the solute. We say that we dissolve the solute into the solvent. Some solutions are so common to us that we give them a unique name. A solution of water and sugar is called syrup. A solution of sodium chloride (common table salt) in water is called brine

Desalination of Seawater Project Paper The main concept of this Desalination process is reverse osmosis‚ but we will get into that later. Right now what is probably running through your head is what exactly is desalination. To put it simply desalination is the process to make seawater or otherwise undrinkable water safe to consume. This can be accomplished through a variety of methods such as the simplest but one of the ones that requires a lot of money would be distillation. Distillation is commonly
