求解化学题,求解每步方程式 ,题目如图
1)2Ag+ +CO32- =Ag2CO3↓
2)Ag+ +NH3·H2O =AgOH↓+NH4+ ,AgOH↓+2NH3·H2O =[Ag(NH3)2]+ + OH- + 2H2O
总:Ag+ + 2NH3·H2O =[Ag(NH3)2]+ + 2H2O
3)Ag+ +Cl- =AgCl↓
4)Ag+ + 2NH3·H2O =[Ag(NH3)2]+ + 2H2O
5)Ag+ +Br- =AgBr↓
6)2Ag+ +S2O32- =Ag2S2O3↓
Ag2S2O3 + 6S2O32- =2[Ag(S2O3)2]3-
7)Ag+ +I- =AgI↓
8)Ag+ +2S2O32- =[Ag(S2O3)2]3-
再问: 最后还漏了一个,加入0.1mol每升的na2s
再答: 2Ag+ +S2-- =Ag2S↓ 看错试题: 1)2Ag+ +CO32- =Ag2CO3↓ 2)Ag2CO3+ +2NH3·H2O =2[Ag(NH3)2]+ + CO32- 3)[Ag(NH3)2]+ +Cl- =AgCl↓ +2NH3 4)AgCl↓ + 2NH3·H2O =[Ag(NH3)2]+ + 2H2O +Cl- 5)[Ag(NH3)2]+ +Br- =AgBr↓+2NH3 6)AgBr↓+ 2S2O32- =2[Ag(S2O3)2]3- +Br- 7)[Ag(S2O3)2]3- +I- =AgI↓+ 2S2O32- 8)AgI↓+ 2S2O32- =2[Ag(S2O3)2]3- +I- 9)2[Ag(S2O3)2]3- +S2- =Ag2S↓+ 4S2O32- 上面解答是分别加入 下面回答是连续加入
