Water-Wine-Milk-Beer Demo

I have the directions for a "water-wine-milk-beer" demonstration.  It is one that was given to me by another teacher.  You may find it useful. The demonstration works as follows:

  1. Begin with a tumbler containing "water". The solution is not really water. Prepare ahead of time a glass 3/4 full of water. To this add 20 to 25 mL of saturated sodium bicarbonate and 20% sodium carbonate solution. (pH = 9)
  2. Pour the "water" into a wine glass.  The wine glass should contain a few drops of phenolphthalein indicator.
  3. Pour the "wine" into a second tumbler.  The second tumbler should contain 10 mL of saturated barium chloride solution.
  4. Pour the "milk" into a beer mug.  The beer mug should contain a very few crystals of sodium dichromate. Just prior to doing the demonstration, add 5 mL of concentrated hydrochloric acid.


I hope you find this useful,
