Quiz
1. Deadly lead(II) acetate is sometimes called "sugar of lead" because it has a very sweet taste; it was once used to sweeten wine! Lead(II) acetate is written as:
Pb(C2O4)2Pb(C2H3O2)2PbC2O4PbCO3PbC2H3O2
2. 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-OH-HO2-HO2+HO3-
3. Sodium bicarbonate is "baking soda", the active ingredient in many antacids. The formula of the bicarbonate ion is:
HCO32-H2CO3-CO32-(CO3)24-HCO3-
4. Hypobromite compounds are used to treat water supplies that are heavily contaminated with bacteria. The formula of the hypobromite ion is:
BrO2-BrO2-2BrO3-BrO-HBrO-
5. 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-ClO32-ClO3-ClO4-2ClO2-
6. Periodate ion is used in staining procedures that improve the quality of microscopic images. The formula of the periodate ion is:
IO4-2HIO3-IO4-IO32-IO3-
7. Perchlorate compounds are used in explosives and jet fuels. The formula of the perchlorate ion is
ClO3-ClO4-2ClO32-HClO3-ClO4-
8. Veterinarians administer an 0.2 percent potassium permanganate solution to cows and horses as an antidote for plant alkaloid poisoning. A bottle that contains potassium permanganate solution might be labelled:
K2MnO3K2MnO4KMgO4KMnO4KMnO3
9. Ammonium nitrate is used as a fertilizer by farmers and as an explosive by terrorists. The formula of ammonium nitrate is
NH3NO3AmNO2NH3NO2(NH4)2NO2NH4NO3
10. Nitrates are used in making rocket propellants, fertilizers, dynamite, and fireworks. The formula of the nitrate ion is:
NO3-NO32-N2O3-2NO2-NO4-
