Question

which solution would be considered acidic?
ph = 7
ph = 8
ph = 3
ph = 12

Explanation:

To determine an acidic solution, we use the pH scale: solutions with \( \text{pH} < 7 \) are acidic, \( \text{pH} = 7 \) is neutral, and \( \text{pH} > 7 \) are basic. Let's analyze each option:

• \( \text{pH} = 7 \): Neutral (not acidic).
• \( \text{pH} = 8 \): Basic ( \( 8 > 7 \) ).
• \( \text{pH} = 3 \): Acidic ( \( 3 < 7 \) ).
• \( \text{pH} = 12 \): Basic ( \( 12 > 7 \) ).

So the solution with \( \text{pH} = 3 \) is acidic.

Answer:

The correct option is the one with \( \text{pH} = 3 \) (the third option: \( \boldsymbol{\text{pH} = 3} \)).
