Quiz
1. Chlorine dioxide is used as an oxidizing agent in many industrial processes. Because it is explosive, it is never shipped, but prepared as needed by a reaction involving the more stable chlorate ion. The formula of the chlorate ion is:
ClO32-ClO4-2ClO2-ClO4-ClO3-
2. Sodium peroxide can be used for oxygen generation in diving bells and submarines, since it reacts with carbon dioxide and produces oxygen gas. The peroxide ion has the formula:
O2-O22-O2-O3-O2+
3. The SCN- ion forms a bright red complex with iron(II) ions. The SCN- ion is called the:
thiocyanate ioncyanide ionthiocyanite ionthiocyanide ionsulfurocyanide ioncyanate ion
4. Nitrite ion is used in bleaching, dyeing and printing fabrics. The formula of the nitrite ion is:
N2O3-2HNO4-NO2-NO42-NO3-
5. Hydroxide ion solutions are sprayed on pretzels to give them their characteristic texture; the ion is removed by reaction with carbon dioxide during baking. The hydroxide ion is:
HO2-HO3-HO2+OH-HO2-
6. Sodium aluminate is used in fabric printing processes. If the formula is NaAlO2, the charge on the aluminate ion must be:
-1-2+1+20
7. A sudden surge in the concentration of thiosulfate ions in geyser water may be a sign that a volcanic eruption is imminent. The thiosulfate ion is:
SO42-SO32-S2O32-S2O4-S2O42-
8. Ammonium nitrate is used as a fertilizer by farmers and as an explosive by terrorists. The formula of ammonium nitrate is
NH3NO2NH3NO3(NH4)2NO2NH4NO3AmNO2
9. Hypochlorite ion is the active ingredient in Chlorox bleach. The formula of the hypochlorite ion is:
ClO-ClO3-HClO-ClO2-2ClO2-
10. Dichromate ions are used in the tanning of leather. Dichromate ion is:
HCrO4-HCrO3-Cr2O72-CrO42-Cr2O32-
