Summer Strong Oxidizers Flashcards
MnO4- (permanganate) in acid solution → ?
→ Mn2+ + H2O
→ manganese (II) + water
What are the weak oxidizing agents?
Metal “ic” ions → “ous” ions
e.g. Fe3+ → Fe2+
and
H2O → H2 + OH-
MnO2 (manganese II oxide) in acid solution → ?
→ Mn2+ + H2O
→ manganese (II) + water
Do MnO4- (permanganate) and MnO2 (manganese oxide) in acid solutions produce the same products?
Yes; → Mn 2+ and H2O
→ manganese (II) + water
MnO4- (permanganate) in neutral or basic solution → ?
→ MnO2
→ manganese (IV) oxide
Cr2O72- (dichromate) in acid solution → ?
→ Cr3+ + H2O
→ chromium (III) + water
Cr2O72- (dichromate) with a base → ?
→ CrO42- + H2O
→ chromate + water
CrO42- (chromate) in basic solution → ?
→ CrO2- + H2O
→ chromium oxide ion + water
Do dichromate with a base and chromate in a basic solution produce the same products?
No.
Cr2O72- (dichromate) + base → CrO42- (chromate) + H2O (water)
and
CrO42- (chromate) + b sol’n → CrO2- (chromium oxide ion) + H2O (water)
concentrated HNO3 (nitric acid) → ?
→ NO2 + H2O
→ nitrite + water
dilute (e.g. 6M) HNO3 (nitric acid) → ?
→ NO + H2O
→ nitrogen monoxide + water
hot, concentrated H2SO4 (sulfuric acid) → ?
→ SO2 + H2O
→ sulfur dioxide + water
Free halogens (e.g. Cl2) → ?
→ Halide ions (e.g. Cl-)
H2O2 (hydrogen peroxide) in acid solution → ?
→ H2O
→ water
Which strong oxidizer produces water (H2O)?
H2O2 (hydrogen peroxide) + acid sol’n → H2O
