How do you standardise potassium manganate solution?
• I am planning a titration in order to determine the number of moles of water of crystallisation in sodium carbonate using HCl. I need to acknowledge any possible chances of inaccuracy in the equipment or method process (since I know that a burette has a low error margin), and any safety measures that need to be taken besides the usual lab procedures. Please help! • I have a chemistry practical to plan. I have to determine the formula of hydrated sodium carbonate by titrating. I was wondering if you could explain how I would decide on the quantities and chemicals I would use in the titration? • In my individual experiment, I tested the decomposition of hydrogen peroxide using 20 vol H2O2. I tested the H2O2 at different concentrations by diluting them with distilled water. (see the following) 1. 5 ml H2O2 + 0 ml distilled H2O 2. 4 ml H2O2 + 1 ml distilled H2O 3. 3 ml H2O2 + 2 ml distilled H2O 4. 2 ml H2O2 + 3 ml distilled H2O 5. 1 ml H2O2 + 4 ml distilled H2O How do I calculate the con
