Quiz
1. Sulfite ion is often used to "fix" photographic film during development. The formula of the sulfite ion is:
HSO4-SO32-SO42-SO3-S2O3-2
2. if AsO43- is the arsenate ion, the name of the AsO33- ion is expected to be:
perarsenatehypoarsenitearsenitehemiarsenatearsenide
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-ClO2-ClO3-ClO32-ClO4-2
4. The SCN- ion forms a bright red complex with iron(II) ions. The SCN- ion is called the:
thiocyanate ionthiocyanide ionthiocyanite ioncyanate ioncyanide ionsulfurocyanide ion
5. Periodate ion is used in staining procedures that improve the quality of microscopic images. The formula of the periodate ion is:
HIO3-IO4-IO32-IO4-2IO3-
6. Sodium aluminate is used in fabric printing processes. If the formula is NaAlO2, the charge on the aluminate ion must be:
-1+10-2+2
7. Sodium acetate is used in chemical handwarmers and heating pads because it gives up a large amount of heat when it changes from a liquid to a solid. The formula for this compound is:
Na2C2H3O2Na2C2O4NaC2H4ONaC2H3O2NaAc2
8. Hypochlorite ion is the active ingredient in Chlorox bleach. The formula of the hypochlorite ion is:
ClO2-2HClO-ClO2-ClO-ClO3-
9. 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:
OH-HO2-HO2+HO3-HO2-
10. The NO4- ion exists in small quantities in the upper atmosphere. Using the naming guidelines for polyatomic ions, the name of this ion would be:
nitratenitritesupernitratepernitratehyponitrite
