CH 204- Introduction to Chemical Practices Experiment 1- Qualitative Analysis of Cations Sharon Alexander Kathrynn Labat TA: Yu-Chun Lin September 25, 2017 Results & Discussion This experiment was composed of three parts. In the first part, qualitative methods were used to identify the unknown cation in an aqueous solution. The cation was to be either lead or silver. If silver was present, extra steps were needed to be taken in order to confirm its presence in the…

Tyler White CHEM151LL 13851 07/18/2017 Mole to Mole relationship and Empirical formula of a Hydrate Purpose: The purpose of this lab experiment is to determine the molar ratio between substances, and to write chemical equations. The second experiment is to determine the ratio of water in copper, and magnesium, which is obtained through burning the vapor using the Bunsen burner. Materials: Because the experiments were conducted online there wasn’t any use of materials, only digital ones, for…

What are buffer solutions? Buffer solutions are solutions in water that mark the mixture of acids and bases. They assist in neutralization response to a certain quantity. Acidic buffer answers are those that have robust acids and weak bases as their components. they're used for neutralizing alkaline solutions. Alkaline or primary buffer answers are those who have sturdy alkalis and weak acids within themixture. they're used for neutralizing acidic aqueous answers. Buffer solutions in the blood…

ANALYTICAL METHODS Determination of λ max Gemifloxacin mesylate λ max is determined by preparing one standard concentration of 10μg/ml and scanning should be done. Preparation of 0.1N HCL 8 ml of hydrochloric acid is taken in 1000ml volumetric flask and dissolved with distilled water and then make up to 1000ml with distilled water. Standard graph of Gemifloxacin mesylate: The λmax of Gemifloxacin mesylate in 0.1N HCL was scanned in UV-Visible Spectrophotometer and found to have maximum…

Chemistry plays a vital role in everyday life even though it may not seem like it. One of these things include firearms, which exhibits chemistry throughout the whole entire process. They show chemical and physical properties ranging from the gunpowder to the actual process of firing a bullet. Gunpowder is what makes the whole reaction occur. Without the use of chemistry throughout a firearm, would make it useless and it wouldn't work. These uses of chemistry occurs so fast that you may not…

How To Pass A Hair Follicle Drug Test Used by employers, corporations, law enforcers, and even parents, hair drug testing is one of the growing methods for drug testing. With it, someone can be tested for drug use as far as 90 to 120 days ago. And unlike urinalysis, there’s no way to adulterate or dilute the hair samples to mislead the results. Now, you might be worried and asking: “How do I pass a hair drug test test!?” First off, know that this isn’t a fool-proof method, but many have had…

concentration of the sodium hydroxide solution in part one of the experiment. It was known that the potassium hydrogen phthalate and sodium hydroxide should have had a 1:1 stoichiometric molar ratio. Potassium hydrogen phthalate was used as the primary standard because it is a very pure concentrated substance that can be predicted. However, the sodium hydroxide is too difficult to be measured because of its tendency to absorb water vapor. This is one area where error can be noted; at times the…

Lab 1 – Ion Exchange Chromatography Danielle Small John Wright 20/01/2016 Introduction: This lab will use ion exchange chromatography – a process in which differently charged ions are separated, by altering the pH of the solution; which shifts the equilibrium of the molecules. During this lab we will separate two compounds from one solute that will be formed by amalgamating a ‘slurry’ – provided by the instructor. Resin or cellulose is used to create a sound support unit in order maintain a…

Equipment: // Sodium thiosulfate solution (of concentrations 0.1M, 0.2M, 0.3M, 0.4M). // Hydrochloric acid (2M). // 100cm3 conical flask. // 10cm3 measuring cylinder. // Dropping pipette. // Small piece of plain paper with a large X drawn with think black pen. // Stopwatch. // Goggles. Variables: Independent - The concentration of sodium thiosulfate solution (0.1M, 0.2M, 0.3M, 0.4M). Dependent - The time taken for the cross to not be seen. Control - // Concentration and volume hydrochloric…
