Colloidal chemistry

Water is a very important resource, every life depends on fresh water to survive. There are three per cent of fresh water of the world’s water and all life on earth can only depends on half of it. Water has become a very fragile resources because, people have damaged the water bodies badly from the use of chemicals, irrigation to household. Consequently, these reasons have severely affected the water, the environment and many lives on earth. Industrial wastes link to a significant cause of damaging

Introduction: In order for this experimental investigation to be conducted successfully with maximum efficiency, chemical theories must be accurately applied. For this investigation, various concepts and theories will be discussed and applied to the two methods- gravimetric and colourimetric- of analysing the precipitate and solution created. One specific variable will be chosen to be manipulated in order to study and analyse. From this, the most effective and accurate method of analysis of percentage

performance I could tell chemical engineering is the path I need to pursue. Chemical engineering has been my passion since high school. Chemical engineering focuses more on experimenting the interaction of chemicals using the knowledge of mathematics and chemistry in order to come up with products that can solve problems in a society. If we

A chemical reaction is the interaction of two or more chemicals that produces a new chemical compound, most reactions require an increase in temperature, pressure, surface area, concentration or the inclusion of a catalysts to speed up the rate of reaction. Chemical reactions can be found in everyday life, without many of us knowing. Either it be a soluble tablet in water, or photosynthesis in a plant. The prerequisites for a reaction are known as the 'Collision Theory '. As stated by M. Ferguson

Calorimetry and Hess’s Law Experiment 10 CHEM 117-515 Samantha Miller* and Emily Duff Summary: The purpose of this experiment was to determine the heat of combustion of magnesium using Hess’s Law. This experiment was significant in understanding how heat can be absorbed or released and how using a calorimeter can help measure heat flow. Part A of this experiment used two dry Styrofoam cups and a magnetic stir bar to create a calorimeter. Temperature was measured and distilled water was placed into

Jacqueline Kang 2-8-2015 Bio 203 Lab Experiment 2: Introduction: The lab was interesting as the main idea seemed to be the proper use and importance of a spectrophotometer but was completed in such a bizarre manner that I am unsure as to wether this was the original purpose or not. The first portion of the experiment seemed to be a practice 10 fold serial dilution using the chemical bromophenol blue, and was treated as a quantitative experiment. The second portion of the experiment used known

As a contemporary writer observing the timeline of modern science, and all the abridgments made to it over the past few centuries, one cannot help but ponder upon the course that science took to reach what it is today. We are aware of the pioneers of science such as Newton, Lavoisier, Stahl, Joule, Maxwell, Einstein etc, and all of the groundbreaking contributions these extraordinary individuals made to mould science into what we today know it to be. Over the course of History of Science, we have

Abstract The process of gravimetric analysis was successfully illustrated through a precipitation reaction using NaCl and AgNO3. These reactants are found in abundance in a laboratory and aimed to produce the precipitate silver chloride (AgCl). This slightly soluble substance is effortlessly precipitated from a single reagent. Silver Nitrate is also not too hard to filter, dry and measure the weight. Introduction An ionic compound is formed when two ions in space of the opposite charges come together

As Director of Laboratory Services it is our job to work closely with all staff, department directors and physicians. As Director it is his or her job to ensure the highest standards of quality are maintained. The department’s job is to manage, update and take responsibility for the quality of laboratory work processes. Prepare budget for the costs, of all personnel, equipment, and supplies. As Director of Laboratory Services communication and interpersonal skills are a necessity for running a successful

overall lesson the reader is supposed to attain. In chapter three, the elements hold a meeting for Julie, however they call her "Human!". She 's describing her problem in her world to the elements during the meeting. They trace the issues back to chemistry. Although not officially proclaimed as the problem, but more as a solution. With the help of an old friend, Kalium, Julie is able to try and save the world from the catastrophes of the modern day. In the third chapter, it is revealed to the reader
