Chemistry Essays

Chemistry essays are different from those who are more related to creative writing. They should be based on critical thinking, logic, and proper evaluation. Sometimes these essays are built on solving chemical equations and other problems. You need to have the solid theoretical background to prepare homework which deserves the highest grade. When students cannot cope with the tasks alone, they seek help at writing service. Our company is one of the best in this specialization. We do not only offer free samples on any topic but help with preparing the entire work within the quickest time.

You can find these chemistry samples only at this category of our website. We share the best papers prepared by our qualified experts to attract more customers. If you like the way our texts are written, you can always drop us a line in the online chat, and we will begin solving your assignment. By making order here, you get a 100% guarantee of quality and confidentiality.

Acid-Base Titration Chemistry Formal Lab Writeup by A.Mm

Abstract By using acid-base titration, we determined the suitability of phenolphthalein and methyl red as acid base indicators. We found that the equivalence point of the titration of hydrochloric acid with sodium hydroxide was not within the ph range of phenolphthalein’s color range. The titration of acetic acid with sodium …

The Wittig Reaction - Lab Report

The purpose of this experiment is to synthesize trans-9-(2-phenylethenyl) anthracene from benzyltriphenylphosphonium chloride and 9-anthraldehyde through the reaction mechanism recognized as the Wittig Reaction. The Wittig Reaction allows the chemist to synthesize phosphoranes in the lab with relative ease. A more recent and inexpensive version of the reaction is the …

Testing for Macromolecules Argumentative

By observing the table above, we could see that Benedict’s test was for reducing sugars, iodine test was for the presence of starch, filter paper was for the presence of fatty acids, and the Biuret test was for amino groups present in proteins. Benedict’s solution was used to test for …

Should Dihydrogen Monoxide be banned?

Before I was able to determine if Dihydrogen Monoxide (DHMO) should be banned from use or not, I had to find out what exactly DHMO was. Dihydrogen Monoxide, also known as Dihydrogen Oxide, Hydrogen Hydroxide, Hydronium Hydroxide, or simply Hydric acid, is a colorless, odorless and tasteless chemical compound. It …

Investigate the effects of osmosis on potato cell sap

I have been asked to investigate the effects of osmosis on potato cell sap. I will test potato cylinders in different strengths of sucrose solution and record any results in a table. I will then analyse my findings and work out the isotonic point of the potato cell sap. Prediction …

The History and Progression of Chemistry

The birth of the modern atomic theory. In 1750, Rudjer Boscovich, a scientist born in what is now Croatia, suggested the theory that atoms were “uncuttable” might have been wrong. Boscovich thought that atoms contain smaller parts, which in turn contain still smaller parts, and so forth down to the …

The Solubility of Potassium Nitrate

Aim: The aim of this experiment is to find out by how much the solubility of potassium nitrate into distilled water increases when the solution is heated, and if yes, by how much. Hypothesis: According to data on the internet, 3.75 × 10­¹ moles of potassium nitrate dissolve in 100g …

The Synthesis and Determination of Empirical Formula for Magnesium Oxide

Aim: To determine the empirical formula for magnesium oxide. Data Collection: Table 1 Mass of empty crucible, crucible + Mg (roughly 1cm pieces of a 15-cm piece of magnesium ribbon), and crucible +MgxOy. (mass measured with an analytical balance). The mass of crucible + MgxOy was obtained after a continuous …

Lab report on a fischer esterfication

Abstract: The objective of this experiment is to efficiently perform a fischer esterification of 1-Hexanol to form water and hexyl acetate, and to confirm the esterification with a nuclear magnetic resonance (NMR) spectroscopy. It was found that 0.3963 grams hexyl acetate was formed with a percent yield of 33.2%. The …

Alkenes by Elimination

Abstract: The objective of this experiment is to successfully perform a dehydration of a 2-butanol and a dehydrohalogenation of 2-bromobutane to form the products 1-butene, trans-2-butene, and cis-2-butene. It was found that a dehydration of 2-butanol yielded 4.6% 1-butene, 67.3% trans-2-butene, and 28.1% cis-2-butene, and a dehydrohalogenation of 2-bromobutane yielded …
