Redox Reactions ACIDIC

Question 1

Nitrate reduction ACIDIC

Answer 1

NO3 -(aq) -> NO(g)

Question 2

Permanganate reduction ACIDIC

Answer 2

MnO4 -(aq) -> Mn 2+ (aq)

Question 3

Dichromate reduction ACIDIC

Answer 3

Cr2O7 2- (aq)-> Cr 3+ (aq)

Question 4

Oxidation sulfite ACIDIC

Answer 4

SO3 2- —> SO4 2-

Oxidation # of sulfur +4–>+6

Question 5

Oxidation hydrogen peroxide ACIDIC

Answer 5

H2O2 (aq) —> O2 (g)
Oxidation # on Oxygen -1–>0
Forms water and oxygen

Question 6

OXALATE
C2O4 2-
Carbons oxidation state?

ACIDIC

Answer 6

+3
Since it would rather be +4, it will oxidize (lose electrons)
C2O4 2-(aq)—> CO2 (g)

Question 7

Chlorine 2Cl -

ACIDIC conditions

Answer 7

2Cl -(aq) —> Cl2 (g)

Should be avoided bc Cl2 is bad

Question 8

When compounds contain PBlock/DBlock metals AND no metals w less positive oxidation states…
In acidic

Answer 8

The metal will be oxidized
Ex. SnCl2
Sn 2+ to Sn 4+
