Ionic Bonds Essay The periodic table is a masterpiece of organized chemical information. It is a table of the chemical elements in which the elements are arranged by order of atomic number. The standard form of the table includes periods (horizontal rows in the periodic table) and groups (vertical rows in the periodic table). Atoms are the basic building blocks of ordinary matter. Atoms are made up of particles called protons‚ electrons‚ and neutrons. Protons carry a positive electrical charge‚

February 2013 CM1191 Experiment 1: Study of Solubility Equilibrium 1. Abstract The aim of this experiment is to determine the relationship between the solubility of potassium hydrogen tartrate (KHC4H4O6) and temperature. Titrate a known concentration of NaOH against a saturated solution of KHC4H4O6 at different temperatures to obtain the concentrations of KHC4H4O6‚ and hence the solubility product constant of KHC4H4O6 at various temperatures. It was found that the solubility product constant

Experiment to investigate the effect of concentration of electrolyte on the current of voltaic cell Aim The aim is to identify the relationship between the concentration of H2SO4 solution and the current of Cu-Zn voltaic cell. Hypothesis My hypothesis is that the greater the concentration of sulfuric acid the bigger the current of the voltaic cell. In a voltaic cell‚ chemical energy is concerted to electrical though the oxidation and reduction happen on the electrodes. Current will not flow

Compare and contrast the structure and bonding in Ionic‚ Covalent and Metallic species. Relate the structure and bonding to the properties of the species. Ionic bonding is usually formed between a metal and a non-metal‚ Covalent between two non-metals and Metallic between two metals. Ionic Bonding; Ionic bonds tend to form between metals whose atoms need to “loose” electrons to gain the nearest noble gas configuration and non-metals that need to gain electrons. These electrons are transferred

Introduction For this experiment‚ we are going to determine the effect of temperature on solubility‚ to be done in a chemical by dissolving a solute in a definite amount of solution which is saturated. Specifically‚ the goal of this experiment is to prepare a saturated solution of Na2C2O4 in water at different temperatures‚ determine the effect of temperature in solubility‚ and to apply Le Chatelier’s Principle. We can do all this by simply titrating a certain amount of standard KMnO4‚ and measuring
