Recommended: Chemical reactions 8th grade
In this lab experiment, various solutions of different concentrations were created with Fe(NO3)3 (mL), KSCN (mL), and H2O (mL). When these chemicals were combined, a solution that was pale orange in color was created. These solutions were placed into a Colorimeter and their absorbance values were determined. Once these absorbance values were obtained, many calculations were done, including the Law of Mass Action (Keq = ([C]c x [D]d) / ([A]a x [B]b)) to determine the final answer of 159.7. This value is compared to the accepted Kc value of 133, revealing a percent error of around 20.08%. The purpose of this experiment was to experimentally determine the equilibrium constant (Kc) for the chemical reaction of Fe3+(aq) + SCN-(aq) ↔ FeSCN2+(aq).

Green Frosting Lab Report
616 Words | 2 PagesThe essential points of the green-frosting are the concentration and absorbance value in each diluted which the process of serial dilution. The standard curve of Blue#1 and yellow #5 provide the equation of the trend-line in order to calculate the concentration in the diluted solution of the green frosting. The mole of dye in 100mL green stock solution, mole of dye in 5 gram and 1 gram of frosting, the Beer –Lambert Law, and the compare to amount desired by the company can be determined. The Beer-Lambert Law is the relationship between color and the concentration and equation A=Ebc. The “A” is absorbance, the “C” is a concentration in molarity, the “E” is a molar absorptivity and “b” is the path-length. The goal of the lab is to use the absorbance and the Beer-Lambert law to determine the amounts of blue#1 and yellow #5 in the green frosting.
Enzyme Formal Lab Report
1157 Words | 3 PagesLiving organisms undergo chemical reactions with the help of unique proteins known as enzymes. Enzymes significantly assist in these processes by accelerating the rate of reaction in order to maintain life in the organism. Without enzymes, an organism would not be able to survive as long, because its chemical reactions would be too slow to prolong life. The properties and functions of enzymes during chemical reactions can help analyze the activity of the specific enzyme catalase, which can be found in bovine liver and yeast. Our hypothesis regarding enzyme activity is that the aspects of biology and environmental factors contribute to the different enzyme activities between bovine liver and yeast.

Kinetics Of Ester Hydrolysis Catalyzed By Digestion
1506 Words | 4 PagesThe purpose of the experiment is to study the rate of reaction through varying of concentrations of a catalyst or temperatures with a constant pH, and through the data obtained the rate law, constants, and activation energies can be experimentally determined. The rate law determines how the speed of a reaction occurs thus allowing the study of the overall mechanism formation in reactions. In the general form of the rate law it is A + B C or r=k[A]x[B]y. The rate of reaction can be affected by the concentration such as A and B in the previous equation, order of reactions, and the rate constant with each species in an overall chemical reaction. As a result, the rate law must be determined experimentally. In general, in a multi-step reac...
Equilibrium Constant Lab Report
478 Words | 1 PagesThe objective of this lab is to find the equilibrium constant of Fe(SCN)2+ through multiple trials using a spectrometer. Since one chemical is colorless and the other is colored a spectrometer can be used to monitor amounts of each in the solution. By completing multiple trials an average can be reached for the value of the equilibrium constant of Fe(SCN)2+.

Solid Compound Lab Report
336 Words | 1 PagesTo begin the experiment, approximately 0.01g of the known solid compound was obtained in a test tube. The relative quantity was then observed and about 1mL of water was added. The test tube was then agitated for approximately twenty seconds and the quantity of solid visible was observed and subsequently contrasted to the original volume. Next, it was determined if any solid appeared to have dissolved in the water. After having determined if the solid dissolved, additional crystals were introduced into the test tube in order to determine if the solid was slightly soluble, soluble or very soluble. If the solid dissolved, the pH of the water was tested using the pH strips and the existent color change or lack there-of was observed. This process

In order to execute this, biochemical tests of various magnitudes are used to identify what a patient may be infected with. In our lab, we received an unknown sample of urine. After several biochemical tests, we determined our unknown specimen to be Enterobacter aerogenes.
Enzyme Lab Report
406 Words | 1 PagesMy hypothesis was I think that if we change the temperature of the enzyme it will have an area where the enzyme works very well, but if we increase or decrease the temperature too much, it will slow the productivity. If we change the pH of the enzyme, there will be an area where it is extremely productive, but if it gets too acidic or basic the productivity will slow. If we change the concentration by increasing the amount of enzymes, it will be more productive. T think this because your are having more than 1 enzyme work on one task. I you decrease the amount of enzymes, the productivity will be slower because there are less enzymes working on that certain task. The data refutes my hypothesis because I found that the enzymes work best in one
The Titration Of Oxalate
1107 Words | 3 PagesFrom this, the exact formula for the coordination compound can be found using several methods. To find the amount of iron (III) spectrometry will be used. When iron is mixed with sylic acid it makes a deep purple color by measuring the absorbance of the mixture the mass of iron can be found using Equation 2.

2827 Words | 6 PagesTo a solution of (NH4)2Fe(SO4)2 • 6H2O (dissolved in 20ml water) 1 ml of sulphuric acid was added and stirred. The oxalic acid (dissolved in 25ml water) was also added and this combined solution was slowly heated to boiling, resulting in the formation of yellow iron(II) oxalate precipitate. The liquid was decanted and 15ml of hot water was added again to the precipitate, this was stirred and filtered. The precipitate (iron(II) oxalate) was transferred to another beaker and a potassium oxalate solution (dissolved in 10ml hot water) was added.
