INTRODUCTION 1.1What is an acid-base titration? An acid –base titration is the determination of the concentration of an acid or base by neutralizing the acid or base with an acid or base of known concentration. An acid-base titration is the analysis of the concentration of acids and bases; through this process an acid or base of known concentration neutralizes an acid or base of unknown concentration. The neutralization of an acid or base in acid-base titration can be measured with either a…

Prac 18 – Reaction Rate of Notongooglenium – Angus Dally Research Question: How does the presence of a Notongooglenium oxide catalyst effect the rate of hydrogenation of ethenol (vinyl alcohol)? Aim The aim of this experiment is to find the effect of the manganese oxide catalyst, a similar compound to Notongooglenium Oxide, on the rate of hydrogenation of ethenol (vinyl alcohol). Introduction Notongooglenium Notongooglenium is a newly discovered element with an atomic number of 24.5. Due to its…

tremendously through different courses and styles of lab reports. Initially I started off in my undergraduate studies by writing a few biology lab reports in my courses, however chemistry lab reports are not comparable to these lab reports, in which the content and structure are different. Once I got used to writing chemistry style lab reports, the format and style of writing changed again when I reached Quantum Mechanics. As I had taken Quantum Mechanics before this writing intensive…

A thing I learned about Kelsey is that she hates chemistry, and that was the main problem she faced. Struggling through general chemistry 1 and 2, and currently taking organic chemistry, it has taken a toll on her. What she does not like about the program (giving her the reason to switch from a BS to a BA) is that she had to take classes that she did not need for grad…

Freezing point is the temperature for a particular compound where the liquid freezes to form a solid (Chemistry Dictionary). If salt is added to water, it freezes at lower temperatures. If there are fewer water molecules, then freezing occurs at a slower rate (Salt and the Freezing Point of Water). Pure water freezes at 0º Celsius, but water that is combined with salt will freeze at a temperature less than 0º Celsius (Oleson, Andrew and Daly, Terik). A solvent is something in which other things…

chemist from Russia who lived in poverty and was the only one of seventeen siblings to attend school. Mendeleev then created the first periodic table from his finding through periodic law, which he also created. Medeleev was a major contributor to chemistry through the modern…

Every person in the world has some sort of interests whether it’s reading or playing soccer. Athletics is defined as, physical sports and games of any kind. In my case I am very interested in sports. I’ve been an athlete for as long as I can remember. Athletics is way for me to escape and forget about everything for a while. Playing sports has taught me how to focus only on what I am doing. For instance, I did cheerleading for eleven years of my life and during competitions I had to perform a…

Iodine clock reactions also known as Landolt Clock Reactions are one of many types of reactions in Chemistry. Clock reactions are an appealing way to show different type of chemicals having a reaction towards each other. This type of chemical reaction shows the demonstration of chemical kinetics. Iodine clock reactions were discovered by Swiss chemist Hans Heinrich Landolt in 1886. The procedure of conducting an iodine clock reaction consist of two colourless chemicals being mixed together.…

Antacids are essential in science and everyday life. They work to neutralize an acid in a reaction. Antacids are bases and the chemistry definitions of a base vary. A base is defined as a substance that produces OH- ions in solution in the Arrhenius definition. There is also the Bronsted Lowry definition and the Lewis definition. They are defined as the following respectively: a proton acceptor or H+ ion acceptor and an electron pair donor. These terms are used interchangeably to figure out if…

Jacob Schuster Comparing and Contrasting Michael Faraday and Hans Christian Orsted Michael Faraday and Hans Christian Oersted were both Chemists and Physicists in the 1800’s. They both discovered the connection between magnetism and electricity. This paper will give backgrounds on both Faraday and Oersted and will compare and contrast their works. Michael Faraday was born in London on September 22, 1791. He was the first person to produce an electric current from a magnetic…
