Hello, I have a question about the chemistry problem : Redo
rection, can you help me for two questions:
(1) I- + ClO3-1 ---->
I3-1 + Cl-
Why the answer add OH- : 6e- +3H20 +
ClO3-1 ----> Cl-1 +
6OH-
And why not add H2O : 2e- + 3H++
ClO3-1----> Cl-1 + 3H2O
(2) I do not know how to do this Redo reaction:
Ag + HNO3 ----> AgNO3 + H2O + NO
Thanks a lot!
