reading quiz - chapter 2 question 7
part a
if a solution has a ph that is lower than 7, the solution is
○ acidic
○ neutral
○ alkaline
○ a buffer

Explanation:

In the pH scale, a solution with a pH of 7 is neutral. A pH value less than 7 indicates a higher concentration of hydrogen ions ($H^+$), which is the characteristic of an acidic solution. A pH greater than 7 would be alkaline, and a buffer is a solution that resists pH change, not defined by a specific pH less than 7. So the solution with pH lower than 7 is acidic.

Answer:

A. acidic
