| Abstract: | The present analytic methods of the error are investigated and to a improving method is given. Weighing weight method for adding NaCl solution can cancel the accidental error of moving the solution tube. The electric potential titration method instead of the heterometric method and atomic absorption method eliminates systematic error caused by silver chlorate partial dissolving. The high accuracy is showed by this new method. |
