Quiz
1. NaClO4 is used to manufacture explosives. NaClO is the active ingredient in Chlorox bleach. The names of the anions in these compounds are, respectively,
perchlorate and hypochloritequadrochloroxide and monochloroxide
tetroxychlorine and monoxychlorineexochloride and endochloride
hyperchlorite and hypochloritechlorate and chlorite
2. 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
BrO32-HBrO3-BrO3-BrO4-2BrO4-
3. 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:
KMnO3KMnO4K2MnO4KMgO4K2MnO3
4. If the selenate ion has formula SeO42-, the selenite ion might be:
SeO43-SeO4-SeO52-SeO4+2 SeO32-
5. Nitrite ion is used in bleaching, dyeing and printing fabrics. The formula of the nitrite ion is:
HNO4-NO3-NO2-N2O3-2NO42-
6. Stable compounds containing the iodite ion have never been prepared. The formula of the iodite ion could be:
IO3-IO2-IO2-2HIO3-IO2-
7. NaClO3 has been used in herbicides and in explosives. The name of this compound is:
sodium chloratesodium chloritesodium chloride trioxidesodium chloridesodium perchlorate
8. Hypobromite compounds are used to treat water supplies that are heavily contaminated with bacteria. The formula of the hypobromite ion is:
BrO-HBrO-BrO2-2BrO2-BrO3-
9. Chlorite compounds are extremely explosive when they come into contact with combustible material. The formula of the chlorite ion is:
ClO2-HClO3-ClO2-2ClO3-ClO2-
10. 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:
ClO2-ClO4-2ClO3-ClO32-ClO4-
