Determine whether each reaction is a redox reaction. For those reactions that are redox reactions, identify the substance being oxidized and the substance being reduced.
(a) Zn(s) + CoCl2(aq) → ZnCl2(aq) + Co(s)
(b) HI(aq) + NaOH(aq) → H2O(l) + NaI(aq)
(c) AgNO3(aq) + NaCl(aq) → AgCl(s) + NaNO3(aq)
(a) 2 K(s) + Br2(l) → 2 KBr(s)
a) Zn(s) + CoCl2(aq) → ZnCl2(aq) + Co(s).
Zn reduced, Co oxidized
Zn has an oxidation state of zero on the left and +2 on the right. Loss of electrons. oxidation....
