others have already commented on the alka seltzer chemisty, but a simpler
and quantitative way of measuring how much alcohol is in the fuel is to
simply mix it with water. Try 9 parts of fuel to 1 part of water in a
graduated cylinder. the alcohol will migrate to the water phase so you
will
see an increase in the height of the water layer at the bottom and a
decrease in the height of the fuel layer if there is significant amount
of
alcohol..

Does this mean that you can use water to REMOVE alcohol from mogas?

Fill the mighty grape. Pour in a gallon of water. Drive around to mix. Drain
the water. Ta-Da.
