27(15分)(1)“酸溶”时加热的目的是加快溶解速率,锌矿粉里PbSO4杂质不溶于稀,故滤液①的主要成分是PbSO4(2)MnO将Fe2氧化为Fe3,在pH-=4时铁元素以Fe(OH3形式存在PH=4时Mn2+与MnO4发生“归中”反应、产生MinO2↓,反应的离子方程式为3Mn2++2MnO4+2H-0=5MnO,,+4H+(3)c(Cd2+)·c(S2)=K,溶液等体积混合后c(S2)=c2、c(Cd2)≤1052,故c≥4×10K(4)蒸发結晶时ZnSO4能发生水解反应Zn(OH2加入可以抑制其水解(5)ZnSO4溶液电解产物有Zn和H2SO4故阳极反应为2H2O-e4H+O2↑,阴极产生(n-m(e2×1.6×10-×6.03×10(6)Zn2+萃取率在PH=3.5时最高,Co2+萃取率受PH影响较小,故溶液PH最适宜为3.5
