Question

What is an inference you can make based on the observation that the region where the BTB wicked into the base was larger than the region it wicked into the acid?

A. The base has a higher pH than the acid.
B. The acid has a higher pH than the base.
C. The base and acid have the same pH.
D. The pH of the base and acid cannot be determined based on this observation.

Answer 1

The observation suggests that the base has a higher pH than the acid.

Step-by-step explanation:

An inference that can be made based on the observation that the region where the BTB wicked into the base was larger than the region it wicked into the acid is that the base has a higher pH than the acid. In a solution, the concentration of hydronium ions determines the pH value, with higher concentrations resulting in lower pH values. Since the BTB wicked more into the base, it suggests that the base has a higher concentration of hydronium ions, indicating a higher pH.
