I'm not A Chemistry teacher, however I did work as an inorganic chemist in another life.
"Neutral means all acidity is neutralized" Yes, but Neutral also means all bases are neutralized.
pH (potential hydrogen) is a measure using a 10 logarithm scale, of the molar concentration of hydrogen ions, in moles per liter. pH 4 is ten times more acid than pH 5 but a hundred times more acid than pH 6. So even a neutral solution has Hydrogen anions but they are in a balance with the cations in the solution.
The concentration of the hydrogen ions is 10−7 gram-equivalents per liter, which corresponds to a pH of 7.

Don't take me wrong, not a knock-down...Acids and Bases, like there salts, don't evaporate, they decompose.
