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?
It matches the universal pH indicator and is indicating the proper pH.
It should completely match the universal indicator key for all pH values greater than 7 (base).
It should completely match the universal indicator key for all pH values.
There was some sort of experimental error, because the indicators should never match.

Answer: "It matches the universal pH indicator and is indicating the proper pH."
Reason: Both indicators giving the same orange–red at pH 2 shows the cabbage indicator is correctly signalling a strongly acidic solution. It does not, however, guarantee it will match the universal indicator at all other pH values (so the other statements are incorrect).
