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(C2H3O2)2PbC2O4PbC2H3O2Pb(C2O4)2PbCO3
2. Sulfite ion is often used to "fix" photographic film during development. The formula of the sulfite ion is:
SO3-SO32-S2O3-2SO42-HSO4-
3. 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:
Na2C2O4NaC2H3O2NaC2H4ONaAc2Na2C2H3O2
