Who was the supreme commander in the olive branch petition? In general, the higher the temperature the faster the reaction. This is because increasing the temperature increases the number of molecules with more kinetic energy, and hence more molecules would have energy greater than the activation energy. In this titration heating of ferrous ammonium sulphate solution is not required because reaction rate is very high even at room temperature.

Also, at high temperatures, ferrous ions may be oxidised to ferric ions by oxygen of air and error may be introduced in the experiment. Oxalic acid is heated before titration with KMnO4 solution because this reaction happens only in certain temperature. The reaction between KMnO4 and oxalic acid is very slow. However, blanching your greens for a few minutes and disposing of the water leaches out roughly one third of the oxalic acid. It is almost impossible to filter the oxalic acid and recover more than about 80 per cent of the carbon tetrachloride.

About 18 per cent remains attached to the anhydrous oxalic acid and evaporates when the oxalic acid is dried. The last 2 per cent is lost by evaporation during the dehydration. Known as a constituent of wood sorrel as early as the 17th century, oxalic acid was first prepared synthetically in
