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 it differs in the fact that there are these covalent bonds attaching the metal to the ligand. For example in iron(II) ion, it exists in...

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 in chemistry. Firstly, is the acid-base titration method which was carried out during this experiment. In an acid-base titration, the acid/base with a known concentration...

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 of hydrochloric acid. Ammonium hydroxide was then titrated slowly into the conical flask and the conical flask was swirled gently to ensure the reaction is...

Chemistry Laboratory Safety Manual And Sample Lab...

SAFETY IN THE LABORATORY Safety in the laboratory must be emphasized. The compounds you will work with do have some hazards associated with them. Therefore, it is important to follow the safety rules outlined in this lab manual. You should assume that all compounds encountered in the laboratory are toxic and handle them accordingly. Safety goggles for eye protection are recommended and lab coats are...

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 involved in making superphosphate fertilizer, including the manufacture of sulfuric acid from sulfur using the contact process. Also in this report will be an outline...
