Quiz
1. 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:
O2-O3-O2+O2-O22-
2. Sodium aluminate is used in fabric printing processes. If the formula is NaAlO2, the charge on the aluminate ion must be:
0+1-1+2-2
3. Nitrite ion is used in bleaching, dyeing and printing fabrics. The formula of the nitrite ion is:
NO42-HNO4-N2O3-2NO2-NO3-
4. 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:
NaC2H3O2NaAc2Na2C2H3O2NaC2H4ONa2C2O4
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:
ClO4-2ClO2-ClO4-ClO32-ClO3-
6. 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:
nitratehyponitritenitritepernitratesupernitrate
7. Sodium sulfate occurs in nature as the minerals mirabilite and thenardite. The formula of the sulfate ion is:
SO32-SO4-S2O3-2HSO4-SO42-
8. Which of the following is the bisulfate ion?
S2O32-(SO42-)2SO42-HSO4-S2O82-
9. 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:
KMnO3K2MnO3KMnO4K2MnO4KMgO4
10. If TeO42- is the tellurate ion, the name of the TeO32- ion is expected to be:
hemitelluratehypotelluritetelluridetelluritepertellurate
