How has the study of chemistry affected the lives of ordinary people? Every single day‚ without even realising it‚ we use so many things that are brought to us by the discoveries and advances in chemistry. Many of these things we take for granted‚ and don’t even bother to question how it got there‚ why it is there‚ and how it works. Chemistry makes up everything in our lives‚ from the air that we breathe‚ to the plastic on the keyboard I’m typing on now‚ and a in depth study of some of the wonderful

Chemistry EEI Introduction: Corrosion is the returning of metals back into their natural constituents when exposed to an atmosphere with which it can react. Both metals and non-metals are able to undergo redox reactions as well as other ceramics and polymers which are known to undergo a similar process which is referred to as degradation. This investigation aims to outline and assess the factors affecting corrosion and explore in depth how redox reactions work. Reduction and oxidization reactions

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‚ reduction has occurred (electrons have been gained). MnO4¯ + 8 H+ + 5e¯ → Mn+²

The Titration of a Basic Solution of Unknown Molarity with a Standard Hydrochloric Acid Solution Abstract The aim of the experiment was how to determine the molarity of a solution. My hypothesis was if I have to determine the molarity of a NaOH solution‚ then I would have to use a standard solution of HCl solution because I would need to neutralize each other to determine the concentration of the solution of NaOH. The method that I used for this experiment was titration. Titration helped
