Question 1
The analysis for iron usually is done by titration with permanganate. Identify the oxidizing agent in the following equation:
MnO
4-(aq) + 5 Fe
2+(aq) + 8 H
+(aq) → 5 Fe
3+(aq) + Mn
2+(aq) + 4 H
2O(l)
◦ MnO
4- ◦ Fe
2+ ◦ H
+ ◦ Mn
2+ ◦ It is not a redox reaction.
Question 2
The mixing of which pair of reactants will result in a precipitation reaction?
◦ CsI(aq) + NaOH(aq)
◦ HCl(aq) + Ca(OH)
2(aq)
◦ K
2SO
4(aq) + Hg
2(NO
3)
2(aq)
◦ NaNO
3(aq) + NH
4Cl(aq)
