A student mixes 50.0 mL of 0.10 M potassium chromate,\(\ce{K2CrO4}\) , solution with 50.0 mL of 0.10 M \(\ce{AgNO3}\) . A red precipitate of silver chromate forms and the concentration of the silver ion becomes very small. Correctly place the concentrations of the remaining ions in order of decreasing concentration.以下是您提供的四个选项的离子浓度大小顺序的 LaTeX 格式：
