3 Preparation of analytical solution
3.1 General requirements
3.1.1 The water used in this part refers to the third-grade water that meets the requirements of GB/T 6682 when no other requirements are specified. When the reagent is not specified
Refers to analytical purity.
3.1.2 When preparing 0.02mol/L or standard solution with a concentration lower than 0.02mol/L, the concentration of the stock should be higher before use.
The solution is accurately diluted with freshly boiled, cooled water for 15 minutes and recalibrated, if necessary.
3.2 Reagents and materials
3.2.1 hydrochloric acid.
