I'm curious to know if the alka-seltzer method is chemically valid, and
why it works -- not just that it works.

Anyone know?

I've got my doubts. AlkaSeltzer fizzes because it contains primarily
citric acid and sodium bicarbonate and these disassociate in the water
and generate carbon dioxide (and sodium citrate). I don't think they'll
disassociate in either gasoline or ethanol. Any fizzing in the
ethanol is probably due to water dissolved therein.
