was obtained from the brass‚ was used to react with iodide to produce iodine. Iodine was then titrated with thiosulfate. In this experiment‚ the amount of titrant dispensed correlates with the amount of copper; therefore‚ the amount of copper in brass was calculated by using the data recorded. In this experiment‚ the analyte is copper and the sample is brass. The concentration range of copper in brass is 50-95%. When copper reacts with iodide it forms a precipitate (CuI) along with iodine. As shown

Oxidation and Reduction Mnemonic: OILRIG Oxidation Is Loss‚ Reduction Is Gain Oxidation → the loss of electrons from an atom or an ion→ always happens at anode (positive electrode) → think anOde (O2 in the electrolysis of water xp) Redox reactions: Reactions involving the transfer of electrons e.g. burning‚ rusting‚ photosynthesis‚ respiration and the browning of apples. happens in three types of reactions: 1. addition of oxygen 2. removal of hydrogen 3. increase in valency (how easily an atom

determine the structure of the major product. Sodium saccharin is made from the base catalyzed de protonation of saccharin. This nucleophilic reaction is special because the nucleophilic atom can be oxygen or nitrogen and the leaving group is iodide ion. The solvent used in this reaction is very important for determining the rate of nucleophilic substitution reaction. Polar protic solvents such as water and ethanol result in bulky solvation shells around the charged nucleophile; this is what
