0.01 M HCl solution has a pH of 2. Suppose that during the experiment, both the universal pH indicator and the cabbage indicator turn orange-red for 0.01 M HCl. What can you conclude about the the cabbage indicator key?
Answer
A
It matches the universal pH indicator and is indicating the proper pH.
B
It should completely match the universal indicator key for all pH values greater than 7 (base).
C
It should completely match the universal indicator key for all pH values.
D
There was some sort of experimental error, because the indicators should never match.
