[求助] bp中碘的检测

BP中碘的检测加入碘化钾,这是为什么,另外最后结果是怎么计算的?
To 10 mL of the injection add sufficient water to produce 50 mL. Add 2.0 mL of 0.001M potassium iodide. Carry out the method for potentiometric titration, Appendix VIII B, using 0.001M silver nitrate VS, a silver indicator electrode and an appropriate reference electrode. Subtract the volume of titrant corresponding to the 2.0 mL of 0.001Mpotassium iodide, determined by titrating a blank to which is added 2.0 mL of 0.001M potassium iodide, and use the residual value to calculate the iodide content.
1 mL of 0.001M silver nitrate VS is equivalent to 126.9 μg of iodide.
Not more than 2.0 mL of 0.001M silver nitrate VS is required (40 ppm).
