补充资料:汞(ⅰ)和汞(ⅱ)的转化
从汞的电位图上可看出,hg22+在溶液中不象cu+那样容易歧化。相反,在溶液中hg2+可氧化hg而生成hg22+:
hg2+ + hg = hg22+
k = [hg22+]/[hg2+] =87
表明平衡时,hg2+基本上都转变为hg22+,因此hg(ⅱ)化合物用金属汞还原,即可得到hg(ⅰ)化合物。
由于hg2+ + hg = hg22+反应的平衡常数较大,平衡强烈偏向于生成hg22+的一方,为使hg(ⅰ)转化为hg(ⅱ),即hg22+的歧化反应能够进行,必须降低溶液中hg2+的浓度,例如使之变为某些难溶物或难解离的配合物:
hg22+ + 2oh- = hgo↓ + hg↓ + h2o
hg22+ + s2- = hgs↓ + hg↓
hg22+ + 2cn- = hg(cn)2↓ + hg↓
