Quiz
1. Ammonium nitrate is used as a fertilizer by farmers and as an explosive by terrorists. The formula of ammonium nitrate is
NH4NO3NH3NO3NH3NO2AmNO2(NH4)2NO2
2. If TeO42- is the tellurate ion, the name of the TeO32- ion is expected to be:
telluritepertelluratetelluridehypotelluritehemitellurate
3. 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:
ClO4-2ClO4-ClO2-ClO3-ClO32-
4. Bromate ion was baked into bread until recently as a preservative; it has been found to cause cancer in laboratory animals. The formula of the bromate ion is
BrO4-2BrO4-BrO32-HBrO3-BrO3-
5. 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:
O22-O2-O3-O2+O2-
6. Iodate ion is used as a disinfectant. The formula of the iodate ion is
IO4-2HIO3-IO3-IO32-IO4-
7. Nitrates are used in making rocket propellants, fertilizers, dynamite, and fireworks. The formula of the nitrate ion is:
NO32-NO2-NO3-N2O3-2NO4-
8. NaClO3 has been used in herbicides and in explosives. The name of this compound is:
sodium chloride trioxidesodium perchloratesodium chloridesodium chloratesodium chlorite
9. Phosphate ion is the most common:
-2 anion+1 cation-1 anion-3 anion+1 anion
10. 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:
SO32-S2O42-SO42-S2O4-S2O32-
