Most people find alkaline taste bitter and "bad tasting". There are some exceptions; shellfish, particularly conch, may have a pH of more than 8.0. This is also the approximate pH of bile, which tastes particularly foul when retching. Crackers made with baking powder or baking soda also may be somewhat alkaline, as is egg yolk. However, your ...

Aeration does not seem to be the way to go. If there are no other ions in the water, electrolysis (Kolbe reaction) would convert the $\ce{HOAc}$ to ethane and carbon dioxide: $$\ce{2CH3CO2^- -> 2e^- + 2CO2 + H3C-CH3}$$ This process could probably be arranged to be done in a pipe with electrodes on the sides, so that the water was treated as it was used, ...

Acetic acid does not form an azeotrop with water and is less volatile than water. So aeration of water would do the opposite - enriching of water by acetic acid due preferred evaporation of water. Reverse osmosis should help, perhaps after neutralization to be mostly in acetate form. The question is, if it is worthy the troubles. The cheaper, easier and ...

Agreed! fig. 4 is closest to correct (though still wrong). fig. 1 is wrong because pH starts at 7, in 0.1 M $\ce{HCl}$. fig. 2 is wrong because pH goes above 7. Because $\ce{HCl}$ and $\ce{NaOH}$ are available in equimolar amounts, the final pH should be near 7, neutral, not well above that! fig. 3 is wrong for the same reason as fig. 2. The fact that fig. ...
