The concentration of an aqueous solution of Fe2+ can be determined by a redox titration with aqueous bromate ion, BrO3⁻:

6 Fe2+ (aq) + BrO3⁻ (aq) + 6 H⁺ (aq) → 6 Fe3+ (aq) + Br⁻ (aq) + 3 H2O (l)


Assume that the black spheres in the buret represent BrO3⁻ ions, the gray spheres in the flask represent Fe2+ ions, the concentration of the BrO3⁻ ions in the buret is 0.120 M, and the volumes in the buret and the flask are identical. What is the concentration of the Fe2+ in the flask, and what fraction of the BrO3⁻ solution in the buret must be added to the flask to react with all the Fe2+ ions?
◦ 0.0400 M Fe2+; 1/18 of the BrO3⁻ must be added.
◦ 0.0200 M Fe2+; 1/3 of the BrO3⁻ must be added.
◦ 0.0200 M Fe2+; 1/18 of the BrO3⁻ must be added.
◦ 0.0400 M Fe2+; 1/3 of the BrO3⁻ must be added.

When Gabriel Fahrenheit invented the first mercury thermometer, he called "zero degrees" the lowest temperature he was able to attain with a mixture of ice and salt. For the upper point of his scale, he used 96°, which he measured as normal human body temperature (we know it to be 98.6° today because of more accurate thermometers).

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.
