Introduction of TOPIC

Method: to identify these chemicals I will carry out two types of test: Flame test and chemical test.

Flame test:

* To carry out the flame test I will dip the metal wire in the roaring Bunsen flame.

* Then I dipped the wire in hydrochloric acid

* Next I placed it into the sample and then I placed it into the roaring Bunsen Flame

* After I recorded the colour of the flame

Safety:

* I wore goggles to protect my eyes from acid (hydrochlori

c acid is corrosive) * When I was not using the Bunsen burner, I

Copper carbonate

Add Acidified silver nitrate

White precipitate

Potassium sulphate

I added Acidified barium chloride solution

White precipitate

Evaluation: Flame test and chemical test tell us which chemicals are present. This is called a qualitative analysis. In industry, it is also very important to know how much of the chemical is present. The difference between my tests and the tests carried out in the industry is that they find the amount as well as the type of chemical.

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 water as Fe(H2O)62+. In this ion, water molecules are arranged about the iron atom with their oxygen atoms bonded to the metal by donating electron pairs to it. A coordination compound is a compound that have either of complex ions and other ions of a neutral species or opposite charge. As an example of coordination compound is the compound K4[Fe(CN)6] which contains the complex ion Fe(CN)6 4- and four K+ ions. Some of the transition elements have biological activity and their role in human nutrition...

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 and fixed volume will be added into the conical flask with a pipette and this would be the solution that is to be titrated. This solution is also known as the titrand. The base/acid with a known concentration but no fixed volume would then be added into the burette. This solution is called the titrant [1]. The point where neutralization is reached is usually indicated by an indicator while in some reactions the solutions are self-indicating. Hence, a small amount of acid-base indicator will be...

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 reacted completely. The titration stops when the colour of the titrand changed from colourless to pale pink. The average titrant (29. 55 mL) of 0. 1 M of ammonium hydroxide was added into the conical flask. By using screened methyl orange as indicator, the average titrant (26. 45 mL) of 0. 1 M of ammonium hydroxide was added to change the colour of the titrand from red to grey in conical flask. In weak acid-strong base titration, 0. 1 M sodium hydroxide ( NaOH )...
