Answer 1:
It depends. If you just want to see the
reaction happen, then a few teaspoons of each
of vinegar and baking soda will be more than
enough to view the reaction.
If you want to be very exact and you want both
your vinegar and baking soda to react completely
with no leftover starting materials, then you
would need an equal number of molecules of vinegar
and baking soda for this reaction. An equal number
of molecules, unfortunately, doesn’t translate to
equal volumes that you can measure out with your
measuring cup. This is because vinegar and
baking soda have different size molecules and also
different densities.
In order to calculate this, you have to know a
few things which you probably haven’t learned yet
in science class including a few concepts called:
balancing chemical equations, dimensional
analysis and molecular mass. Most students
learn these concepts in high school.
The result of these calculations is that you
need about 1.5 teaspoons of vinegar for every
teaspoon of baking soda. I will put the math
in the answer that is posted on the website in
case you want to look at it, but don’t worry if
you don’t understand it yet. You’ll learn these
concepts later. Have fun making your reaction!
