they can - however, whether they work at all or not depends greatly on the quality of the lemons or ACV (apple cider vinegar).
Switchel, or farmers punch as it was called in colonial America has been around as an electrolyte drink since the beginnings of recorded history...
>>"2. Does baking soda in water help, and how much of that to use?"<<
Ted on Earthclinic.com recommends using the ACV, lemon or lime juice with the baking soda... you can find all of his recipes for alkalizing by doing a search on earthclinic... it will even pop up near the top in Google.
He recommends a mix of potassium bicarb with the sodium bicarb in the *drink* for people sensitive to sodium.
I used the drink in this .pdf put together by Evanluck on the askmoreless forum here on curezone.

Our grandparents and great grandparents, especially those who were farmers knew this stuff through and through... though they did not always have what they may have liked to have, they made do with whatever it was that they had on hand and knew how to use it.

Correct your system and the parasites will leave, if that is indeed what you have.
