Chemistry Coursework Aim I am going to investigate which is the best method for determining silver ions in solution. I am interested to see whatever a electrode potential method or a chemical method (e.g. titration) is more appropriate, especially at low concentration. Background Information Redox If we consider the following reaction: 2Na(s) + Cl2(g) --> 2Na-Cl+(s) Salt (Sodium Chloride) is formed when Sodium is added to Chlorine gas. Sodium Chloride is an ionic compound, which is made up of Na+ and Cl- ions. The difference between Na(s) and Na+(s) is that an electron is removed from the Na atom and this a positive charge formed as the number of protons, which are positively charge is not equal to the negatively charged electron. But NaCl(s) is not charged overall, so where is the electron gone? If we look at the equation more closely, we can split the reaction into two parts, and this is...
