Assume that the buret represenst H+ ions, the flask represents OH- ions, and you are carrying out a titration of the base with the acid. If the volumes in the buret and the flask are identical, and the concentration of the acid in the buret is 0.250 M. What is the concentration of base in the flask?
Explain why hydrogen which has one electron in its lowest state, should in principle be a metallic conductor in its solid state whereas helium which has two electrons in its lowest energy state should be an insulator.
