Another color
change?
YOU WILL NEED
→ 2 test tubes with litmus
solution from Experiment 6
→ measuring spoon
→ tartaric acid
→ cup
→ lemon, lemon squeezer
HERE’S HOW
1. Add 1 spoon tip tartaric acid to a test
tube of litmus solution. Swirl the test
tube a little. Is there a color change?
2. Will it also work with fresh-squeezed
lemon juice?
Use a juice squeezer to squeeze half a
lemon and add the juice to a clean,
washed yogurt container. Now add a
few drops of the lemon juice to the
litmus solution in the remaining test
tube.
When you swirl the test tube, you get
another color change to light right. And
it works just as well with the tartaric
acid as with the lemon juice.
