Standardize a solution of potassium manganate(VII) by an iron (II) salt (ammonium iron (II) sulphate) Introduction Oxidation numbers describe the number of electrons the atom will gain or lose during a reaction. Each atom in an equation can be assigned an oxidation number according to certain rules. If the oxidation number of an atom increases as you go from the left side to the right side if an equation‚ oxidation has occurred (electrons have been lost); if the oxidation number decreases

Earth Science is an all-embracing term for the sciences related to the planet Earth. It is arguably a special case in planetary science‚ the Earth being the only known life-bearing planet. There are both reductionist and holistic approaches to Earth sciences. The formal discipline of Earth sciences may include the study of the atmosphere‚ hydrosphere‚ oceans and biosphere‚ as well as the solid earth. Typically‚ Earth scientists will use tools from physics‚ chemistry‚ biology‚ chronology and mathematics

Chemistry and Society According to the Merriam-Webster Dictionary‚ accuracy is “freedom from mistake or error: the quality or state of being accurate: the ability to work or perform without making mistakes” ("accuracy‚" 2014). Precision‚ however‚ is “the quality of being precise” ("precision‚" 2014). That doesn’t really help with the definition much. After subsequently checking the definition for precise it means to be “very careful and exact about the details of something” ("precise‚" 2014). The

Personal Statement The decision to study a Masters degree in Chemistry at university stemmed from my studies of chemistry at GCSE. As someone who is naturally inquisitive‚ I have found that chemistry is a subject which seems to explain the world around me. This interest in chemistry has been encouraged by frequent visits to the Heart Hospital in London from a young age. Through this‚ I have developed a particular interest in the workings of medical equipment‚ especially learning about the theory
