Answer 1

To make it a fair test, I would have multiple tests made and done and recorded to see what the results would be.

Step-by-step explanation:

If you used the scientific method, and make a hypothesis that lactic acid is a weaker acid than hydrochloric acid, then you would make a fair test and find out which is which.
