Quiz
1. Sulfite ion is often used to "fix" photographic film during development. The formula of the sulfite ion is:
S2O3-2SO3-HSO4-SO32-SO42-
2. Perbromate ion is extremely unstable for quantum mechanical reasons. If it existed, the formula of the perbromate ion could be:
BrO3-BrO4-BrO4-2HBrO3-BrO32-
3. Periodate ion is used in staining procedures that improve the quality of microscopic images. The formula of the periodate ion is:
HIO3-IO4-IO3-IO32-IO4-2
4. An old bottle labelled "sodium biphosphate" contains:
NaH2PO3Na3PO4Na2HPO4NaHPO3NaH2PO4
5. Iodate ion is used as a disinfectant. The formula of the iodate ion is
IO4-2HIO3-IO4-IO32-IO3-
6. Stable compounds containing the iodite ion have never been prepared. The formula of the iodite ion could be:
IO2-IO2-2IO3-HIO3-IO2-
7. 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-BrO4-2BrO32-HBrO3-BrO3-
8. if AsO43- is the arsenate ion, the name of the AsO33- ion is expected to be:
hypoarsenitearseniteperarsenatearsenidehemiarsenate
9. Chlorite compounds are extremely explosive when they come into contact with combustible material. The formula of the chlorite ion is:
ClO2-ClO2-2ClO2-HClO3-ClO3-
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-S2O32-S2O42-S2O4-SO42-
