Finding the concentration of an unknown sample of copper sulphate using colorimetry. In this task the concentration of an unknown sample of copper sulphate using colorimetry was used to find the concentration. In this investigation copper sulphate was used which is CuSO4.5H20 as a formula. To make a standard solution which was 1M, the same clean equipment was used to make up the standard solution as used to make sodium carbonate. However there was one difference and that was that the hot distilled
distributed side groups are versatile and therefore help give the desired physical and chemical properties. Properties Of The Primer Layer Amine groups in chains mean that ionic groups are produced when in contact with acid. This makes the polymer soluble in water. When a car is immersed in the primer (containing the ionic polymer and rest of paint) an electrolysis cell is made (car body is cathode). The polymer then becomes electrically neutral and therefore
reacts with sulfur and it makes a compound that is used for organic chemicals. Then when the chemicals are sent to a factory they’ll be turned into organic chemicals. After that the chemists will get it back. It’s a cycle of phosphorus. Phosphoric acid and phosphate rock put together
Empirical Formula Lab Report The purpose of this lab was to determine the empirical formula of copper oxide compound. In the lab, hydrochloric acid and copper oxide compound was mixed until it formed a blue solution. An oxidation-reduction reaction, a reaction in which there is an exchange of electrons between elements, was performed by adding zinc to the solution to displace the copper in copper chloride. Zinc, in this case, was oxidized by losing two electrons (0 → 2+) while copper was reduced
On December 5th, 1952, London began to go through its “I want to resemble a post-apocalyptic city” phase. Smog shrouded the entire city in it’s smothering blanket, and many were hospitalized because of the deadly illnesses they contracted. Others were not as fortunate and turned into one more number on the steadily increasing death toll. Much harm was inflicted onto both the people and environment of London during the worsening conditions of the days that followed the first, and a lesson was learned
Shlomo Akeri Professor: Ansell Pol Sci 186 Flame Retardant Chemicals The chief concern that motivates the authors of the article is the lack of documentation and clarity regarding the toxic level flame retardant chemicals. The factors that raise the levels of specific chemicals to scientific, social movement, and regulatory scrutiny and concern are not well defined. The concern is serious as it the chemicals pose a health threat. The authors advance several theoretical arguments regarding the issue
Group Members: Austin Snyder and Geoff Olson Title: Photoreduction of Fe2+ Effects on salicylic acid and UV radiation Question to study: How to determine the amount of iron (II) in a solution using a Beer’s Law Plot? How to accurately calculate the solubility product constant of iron (II) oxalate using a Concentration vs. Absorbance graph o What does the solubility product constant tell us about iron (II) oxalate? Background Problem: 1.Equation: a.Absorbance = proportionality
of this lab is to observe the chemical changes of multiple single replacement reaction. Materials: Chemicals Laboratory Tools Zinc Chemplate Magnesium Goggles Copper Toothpicks CuSO4 (Copper (II) Sulfate) AgNO3 (Silver Nitrate) HCl (Hydrochloric acid) Procedure: Take a chemplate and put one or two pieces of zinc, copper and magnesium as shown in the figure. Then add 5 to 10 drops of given solutions into each well. Observe the reactions for 10 minutes and record. Data/Observations: Reaction
Analysis/conclusions In conclusion, the charge/roman numeral on copper in copper sulfate is 2+. The percent composition of copper in copper (I) sulfate was 40.58% and in copper (II) sulfate it was 25.46%. Later, I calculated that the percent of copper in the lab was 26.13%. This percent shows that copper (II) sulfate was used in this experiment because 26.13% was closer to 25.46% than 40.58%. If iron (II) sulfate and copper metal is the product of copper (?) sulfate and iron metal, then copper (
Experiment 6A: Williamson Ether Synthesis of Phenacetin Experiment 6A, Williamson Ether Synthesis of Phenacetin, introduces one of the most reliable methods to synthesize an ether used in organic chemistry; in addition to, providing firsthand experience with general synthesis processes. A Williamson ether synthesis, which displaces a halide by an alkoxide anion to form an ether, was used to synthesize phenacetin from N-(4-hydroxyphenyl)-acetamide (acetaminophen) —a common analgesic and antipyretic
