Surprisingly, perhaps, the percent ionization varies considerably as a function of the concentration of the nitrous acid. We recall that this means that the fraction of molecules which ionize, according to equation 2, depends on how many acid molecules there are per liter of solution.

My Chemistry Tutor > Ask Chemistry Homework Questions > AP Chemistry > percent ionization, using Ka value ... I'd check out out your quadratic formula, I think it should be: x2 + 1.5x10-5 x - 1.125E-7 = 0; That will lead the concentration of H+ above. I think your answer about the buffers isn't bad.

4.1.2. Ionization of the Ly emission line region ... Gas in the ionization cone is photoionized by the AGN, while the gas outside the ionization cone is predominantly neutral and will cause absorption of Ly emission when this is observed through the neutral gas. The velocity dispersion of the gas inside the ionization...
