(接上期) 三、有沉淀生成的计算例4 向某浓度的AgNO3溶液中加入未知浓度NH4Cl溶液到沉淀完全为止,所生成溶液质量与原AgNO3溶液质量相等,求NH4Cl溶液的百分比浓度。
(Continued from the previous part) III. Calculation Example of Precipitation Generation 4 Add an unknown concentration of NH4Cl solution to a certain concentration of AgNO3 solution until the precipitation is complete. The mass of the produced solution is equal to that of the original AgNO3 solution. Find the percentage concentration of the NH4Cl solution.
