定量分析中可用AgNO₃溶液滴定Cl^－溶液，加入K₂CrO₄为指示剂，达到滴定终点时溶液体积为50mL，c（Cl^－） = 10^－⁵ mol·L^－¹，AgNO₃与CrO₄²^－生成砖红色的Ag₂CrO₄沉淀。已知K_sp(AgCl) = 1.77×10^－¹⁰，K_sp(AgI) = 8.51×10^－¹⁷，K_sp(Ag₂CrO₄) = 1.12×10^－¹²，根据以上实验操作和有关数据，下列说法正确的是

A．常温下，向含AgCl固体的AgCl溶液中加入NaCl固体，AgCl沉淀的量不变

B．滴定终点时，溶液中CrO₄²^－的浓度约为3.6×10^－³ mol·L^－¹

C．向10mL0.1moL/L AgNO₃溶液中滴加3—5滴0.1moL/L NaCl溶液生成AgCl沉淀，再滴加KI溶液，生成AgI沉淀，能够说明K_sp(AgI)＜ K_sp(AgCl)

D．可用0.1 mol·L^－¹的KI溶液代替K₂CrO₄做指示剂
