5.向Hg2溶液中加入KI溶液时有红色HgI2生成,继续加入过量的KI Hgl溶液时HgI2溶解得无色的配离子。请说明HgI2有颜色而无色的原因。(《无机化学例题与习题》吉大版) 相关知识点: 试题来源: 解析 5.答: Hg2电子构型为 5d1", 配离 Hgl 子中,电子没有 d-d跃迁。 由于 Hg 与I靠配位键结合, 键较弱, 电荷...
在含Hgl2(g)的溶液中,一定c(1)范围内,存在平衡关系:HgI2(s)HgI2(aq);HgI2(aq)Hg2++2I ;HgI2(aq)=Hgl^++l_2Hgl_3 ;HgI_2(aq)+2I^-⇌Hgl_4^(2-) ,平衡常数依次为K0、K1、 K2、K3、K4。 已知lgc(Hg)、lg c(HgI )、lg c(HgI )、lg c(HgI )随lgc(I )的变化关系如图所示,下...
