Aer a lile while, the tablet will start to
fizz. Colorful bubbles will rise to the surface
and then slowly sink back down again. When
the fizzing tablet dissolves, it creates a gas
that carries the bubbles to the top. The gas
escapes, and the bubbles become heavy and
sink. The cool swirling effect occurs because
the oil is thick, or viscous. The oil has a
molecular structure that keeps it from mixing
with the water.
This reaction is similar to the one in the
last experiment. The fizzing tablets contain
sodium bicarbonate (baking soda) and citric
acid. When they come into contact with
water, a chemical reaction occurs between
the baking soda and the acid. The products of
this reaction are sodium citrate and carbon dioxide gas. The sodium
citrate is a weak base which can be used to neutralize stomach acid.
This is why tablets very similar to these tablets are sold as antacids
to reduce stomach acid and ease indigestion. The carbon dioxide gas
is what causes the fizzing bubbles. This is also how baking powder
makes baked goods rise!
