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.

Standardization of Sodium Hydroxide Solution

This report is about how to standardize a Sodium Hydroxide (NaOH) solution by titrating it with pure sample of Potassium acid Phthalate (KHC8H4O4). This experiment has two sections. The first section is to standardize the Sodium Hydroxide by titration. Three sample of 0.7 – 0.9 g of solid KHP are …

Format of an Investigatory Project

With the variety of chemistry project topics it is often difficult to choose what to do. Let me help you out. You want something that is easy to do, is virtually guaranteed to work but that will show the judges away with your incredible chemistry knowledge. This is one of …

Preparation of Bis Acetylacetonao Copper

All metal ions in solution are ‘associated’ with water. The water molecules can also be weakly bonded or more strongly as a ligand to form a complex ion, and these can also present in solid ‘hydrated’ salts of crystallization. E.g Copper(II) nitrate (Cu(NO3) 2.3H2O). A complex ion has a metal …

An Aldol condensation reaction is a very effective way of forming a carbon …

Freezing Point Deperession

Conclusion: My Lab unsuccessfully found the molar mass of the unknown given to us in the lab. We were tasked with finding the molar mass of an unknown compound using the colligative property of Freezing Point Depression. The way we did this was first finding the temperature at which ice …

Simple and Fractional Distillation Experiment

One of the most important tasks in chemistry is the separation of organic compounds which are not usually found in pure form naturally or as products of chemical synthesis. Distillation is a common method for purifying liquids based upon their boiling points and their differences in vapour pressure. Distillation is …

Spectroscopic Study of Cu(Ii) Complexes: Crystal Field Theory

The color of coordination compounds of the transition elements is one of their characteristic properties. These colors are due to the absorption and subsequent emission of light in the visible part of the spectrum. Light in this region of the spectrum caused promotion of d–electrons from a lower to a …

Synthesis of Banana Flavor

Abstract The purpose of this experiment was to synthesize isopentyl acetate via Fischer esterification reaction between acetic anhydride and isoamyl alcohol, using concentrated sulfuric acid as a catalyst. This reaction is characterized by the combining of an alcohol and an acid (with an acid catalyst) to yield and ester plus …

The Effect of Varying Molecular Weights on the Rate of Diffusion

The effect of molecular weight on the rate of diffusion was verified by the 2 tests: the glass tube setup and the water agar-gel setup. In the glass tube setup, two cotton balls were soaked in the solutions of hydrochloric acid (HCl) and ammonium hydroxide (NH4OH) and were simultaneously placed …

Chalk Made Out from Seashells

Nowadays, people are getting to use to collect seashells for fun and for past time. They made decorations, even accessories for a doll out of it and most people collect seashells. Here in the Philippines, people made seashells for decorations and accessories. They made seashells into accessories for them to …
