Question

a substance that is 3 on the ph scale would be a(n)
(options: acid, okay, neutral, base)

Explanation:

The pH scale ranges from 0 to 14. A pH of 7 is neutral. Values less than 7 are acidic, and values greater than 7 are basic (alkaline). Since 3 is less than 7, a substance with a pH of 3 is acidic.

Answer:

acid (assuming the first option is "acid" as per the visible text and context of pH scale: pH < 7 is acidic, pH = 7 is neutral, pH > 7 is basic)
