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.

Inorganic Chemistry

Transition elements contain ions that present in aqueous solution as complex ions. A metal ion with a molecule called a ligand are called complex ion and it attached through coordinate covalent bonds. A complex salt is an ionic compound but

General chemistry - Titration

Introduction Titration is defined as technique whereby one solution of accurately known concentration also known as the titrant is added slowly into another solution of unknown concentration until a neutralization reaction is reached. There are several types of titration methods

Ammonium hydroxide solution

In the strong acid-weak base titration, 0. 1 M ammonium hydroxide ( NH4OH ) was titrated with 0. 1 M hydrochloric acid ( HCl ). 2-3 drops of phenolphthalein were added as indicator into the conical flask which contains 25mL

Production of sulphur dioxide

Introduction Currently, fertilizers used on the West Coast are made and then transported from other parts of New Zealand. Because fertilizers have a reasonably large mass the cost of this transport can be expensive. This report will investigate the processes

Assessing Water Quality in a Stream by Chemical Means

1. Introduction The aim of this experiment was to investigate water quality by chemical tests with which the momentary characteristics of the water could be assessed very precisely. The temperature, turbidity, flow velocity, ph (measures the alkality or acidity), total

Estimating Errors in Chemistry

There are two types of error which occur in measurements: 1. Random Errors Random errors or uncertainties cause repeat measurements to vary and be scattered around a mean value. Averaging a number of readings helps to reduce random uncertainties. Precision
