Copper Sulphate Calibration Aim The objective of this experiment is to determine the unknown concentrations of solutions. Introduction With the use of absorption of light a spectrophotometer sends UV wavelengths through solutions to determine their concentrations. The light absorbed is measured as the atoms‚ molecules and ions absorb the wavelengths of light that the spectrophotometer gives off (Meah‚2013). The level of light transmitted defines the amount of light absorbed‚ for instance‚ the lower

Redox Reactions Reactions involving oxidation and reduction processes are very important in our everyday world. They make batteries work and cause metals to corrode (or help to prevent their corrosion). They enable us to obtain heat by burning fuels--in factories and in our bodies. Many redox reactions are complex. However‚ combustion and synthesis (from elements) are two ordinary examples which require very little description. Just a little more involved are the displacement reactions‚ with

In the novel Copper Sun the viewpoints were taken from a 15-year-old slave girl named Amari‚ and a 17-year-old indentured servant Polly‚ Copper Sun is a story of the struggles in the face of human beings during slave times and a hope for freedom against all odds and circumstances. In the novel the AOI that it is portrayed is the area of Health and social education. I chose this AOI because both Amari and Polly had to adapt to their new surroundings and they also had to learn the routes around the

and nothing more. At night if you were female you got raped often. If you were a male you worked in the rice fields‚ with the alligators and the snakes and if you ever disobeyed or did something incorrect you were wiped and beaten. In the book the copper sun Amari the female protagonist‚ goes through these hardships and has to find some reason to live and fight for her freedom. Amari shows traits of perseverance‚ bravery and strength. But still through all of these things she fights to be free.

The Copper Cycle Alexes Montalvo Chem 1500-10 September 26‚ 2012 The Copper Cycle Introduction: The Copper Cycle is a popular experiment used to determine if an element‚ in this instance‚ copper‚ reverts to its elemental form after a chain of reactions. This experiment is very dangerous because of the reactions between the strong acids and bases. In this experiment I performed a series of reactions starting with

spectrophotometric analysis of copper sulphate Introduction: In the modern usage. The term spectroscopy includes a large group of techniques which differ widely in their mode of application and information they reveal. As a useful working definition‚ spectroscopy is a study of interaction of electromagnetic radiation with matter in the experiment it means it’s the usage of ultra-light to measure the absorbance of the copper sulpate. The regions of the electromagnetic spectrum immediately adjacent

Introduction This lab proposed the question of what happens when copper chloride and iron are combined and what is the balanced equation.By completing this lab‚ the goal was to determine the equation and product for the reaction of iron (Fe) and copper chloride (CuCl2). It was predicted either solid iron or solid copper would form. Methods To begin‚ 6.00026 grams of copper chloride was dissolved in 50ml of distilled water in order to have a solution with charged iron and chlorine atoms. Then‚ 6

Copper Cycle Summary During the copper cycle lab‚ my partners and I performed a series of reactions on copper powder and observed the changes it underwent. For the first step‚ we mixed nitric acid and copper powder‚ and noticed that a yellowish brown gas emerged‚ along with effervescence. The red solid disappeared and became a blue liquid. We know that we produced copper nitrate‚ nitrate gas‚ and water because the only two blue solutions in “A New Language” are copper sulfate and copper nitrate
