University Of London Sir Alexander
607 wordsSir Alexander Fleming was born at Lochfield near Darvel in Ayrshire, Scotland on August 6 th, 1881. He attended Louden Moor School, Darvel School, and Kilmarnock Academy before moving to London where he attended the Polytechnic. He spent four years in a shipping office before entering St. Mary's Medical School, London University. He qualified with distinction in 1906 and began research at St. Mary's under Sir Almroth Wright, a pioneer in vaccine therapy. He gained M. B. , B. S. , (London), with ...

Sir Alexander Fleming Millions Of Lives Penicillin
370 wordsSir Alexander Fleming was born in Lochfield, Scotland on August 6 th, 1881. He attended St. Marys Medical School in London. It was in St. Marys, where Sir Alexander Fleming began his research. Early in his medical life, Fleming became interested in the natural bacterial action of the blood and in antiseptics. He then served in World War I as the captain of the Medical Corps, as he continued his studies and started to work on antibacterial substances which would not be toxic to animal tissues. In...

Volume In Each Burette Number Of Moles Base
530 wordsProblem: When adding acids and bases what is the titration of the two? Amounts of reactants and products in a reaction are commonly investigated in two ways in the lab, gravimetrically (by mass), and volumetric ally (by volume and concentration). Titration is the name we give to the process used to determine the volume of a given solution needed to react with a given mass or volume of a sample. We will use the quantitatively study a neutralization reaction, in a neutralization reaction an acid a...

Acidic Or Basic Groups Added Acid Or Base Solution
301 wordsTitration is the addition of an acidic solution to a basic solution or when you add a basic solution to an acidic solution. Titrations are used to determine the concentration of acids or bases in solution. An example of a titration is when a given volume of a solution of unknown acidity may be titrated with a base of known concentration until complete neutralization has occurred. This point is called the equivalence point and is generally determined by observing a color change in an indicator. F...

H 2 O 2 O 2
828 wordsPurpose - The purpose of this lab is to use a chemical titration to measure and them calculate the rate of conversion of hydrogen peroxide (H 2 O 2) to water and oxygen gas using the enzyme catalase. Hypothesis - The rate of enzymatically-catalyzed reactions can be determined by taking time reactions at different time intervals. When the rates are plotted on a graph, the rate of the reaction is the slope of the linear portion of the curve. To determine a rate, any two points on the straight-line...

Electromagnetic Radiation Physical Properties
1,125 wordsAnalytical Chemistry Untitled Analytical Chemistry Analytical Chemistry is the branch of chemistry principally concerned with determining the chemical composition of materials, which may be solids, liquids, gases, pure elements, compounds, or complex mixtures. In addition, chemical analysis can characterize materials but determining their molecular structures and measuring such physical properties as pH, color, and solubility. Wet analysis involves the studying of substances that have been subme...

Sodium Hydroxide Hydrochloric Acid
600 wordsBack titration: Work to be done: To find out the atomic mass of a substance using a method called back titration. Chemicals and apparatus: Magnesium Beaker Glass Burette Distilled water Methyl red 0. 5 M sodium hydroxide, NaOH 1. 0 M hydrochloric acid, HCl Lab-work: The name of the experiment explains the way of doing it quite well. You do measure how much you have of the substances and then do the titration. My mission was to find out the atomic mass of magnesium. I took a sample and weighted i...
