Terbium is one of the few rare earth radiometals that could be used in nuclear medicine for tumor diagnosis and treatment, due to the favorable physical decay properties such as half-lives, type and energy of emissions. The four Tb radionuclides with higher clinical interest are152Tb and155Tb,...
When I say you can ignore the ionization of the acid I mean that the concentration of HA at equilibrium is equal to the initial concentration of acid. The H+ concentration would still come from the ionization of the acid, but it's just a way to simplify the equation that you'd get.2...
So you need to see what the potential is for oxygen to form rather than hydrogen. The standard oxidation potential for water is -1.23 volts while that for Cl- is -1.36 volts. That is so close that in reality, the chloride is more easily oxidized than the water is so chlorine gas forms...

(The increase is by a factor of about 1020,000,000,000,000, 000,000,000.) Equal volumes of two gases are allowed to mix. The effect is the same as allowing each gas to expand to twice its volume; the thermal energy in each is now spread over a larger volume. One mole of ...
