I think it was Angela Collier that did a pretty basic test with a common store bought alkaline water, a lemon and some test strips. The water doesn’t start very alkaline at all.
She did the math (with some assumptions), but basically 0.25 mL of lemon juice will turn 500 mL of alkaline water into neutral water:
This is in the video at 13:16.
The reason is that pH is a logarithmic scale. Alkaline water has a pH of about 8, which means it has a tenth of the hydrogen ions compared to neutral water at pH 7.
Lemon juice has a pH value of 2, which is 1,000,000 times more hydrogen ions than there are in pH 8. So, you just need a little bit of lemon juice to increase the hydrogen ions in alkaline water tenfold, which makes it neutral.
Even regular neutral water shifts to slightly acidic (5.6) as long as it has contact to air (CO2 dissolving). Would be interesting to know how long those store bought alkaline water becomes base or acidic.

It’s an amusing video.

Facts baby :)
That girl can rant. Love her work, but always watch it at 2x to maximize the frustrated-teacher vibe.
