The labels fell off of three test tubes, each containing a colorless solution. A student knew that one of
the test tubes contained a 0.1M HCI solution (acid), another contained a 0.1M NaOH solution (base),
and the third contained a 0.1% phenolphthalein solution (indicator). To determine the identity of each
solution, the student temporarily labeled the test tubes "A". "B", and "C". The student mixed the
solutions in various combinations, recording the observations in the table below:
Observations after mixing three unknown solutions
