Chemical Periodicity Essay Sample

DATA & RESULTS

According to the data and information shown on the table above the elements shows chemical periodicity. Its shows also that in every group there are similar characteristics that is visible in every element. The Group IA & IIA Elements shows the same characteristics in physical state, color, and appearance but the solubility has some variations. In Group IVA only the physical state are the same while the color and appearance have variations. In Group IIA Metal Oxides shows also similar characteristics in physical state, reaction to blue litmus paper and most especially in red litmus paper that shows a reaction.

MATERIALS / REAGENTS & EXPERIMENTAL PROCEDURE

For the Group IA & IIA Elements, each small amount samples of Li2CO3, Na2CO3, K2CO3, MgCO3, CaCO3 and BaCO3 was place in the different test tubes. After placing them in the test tubes, we identified the physical state, color, and appearance of each. Then we test the solubility of each sample by using a 10mL of water.

For the Group IVA Elements, each small amount samples of C, Sn, Si, and Pb was placed in different test tubes. After placing them in the test tubes, we identified the physical state, color, and appearance of each.

For Group IIA Metal Oxides, a small amount sample of MgO and CaO was placed in different test tubes. 10mL H2O was added to each samples and it was test trough the use of litmus paper. A balanced chemical equation for each sample was written to show the reaction of the oxides and water.

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...
