Question

Rain with a pH of 3 is how many times more acidic than rain with a pH of 7?

A) 10 times
B) 100 times
C) 1,000 times
D) 10,000 times

Answer 1

A solution with a pH of 3 is 10 times more acidic than a solution with a pH of 4, and 100 times more acidic than a solution with a pH of 5.

Step-by-step explanation:

pH is a logarithmic scale that measures the concentration of hydrogen ions (H+) in a solution. A solution with a pH of 3 is 10 times more acidic than a solution with a pH of 4.

Since the pH scale is logarithmic, each unit change in pH represents a tenfold change in acidity. Therefore, a solution with a pH of 3 is 10 times more acidic than a solution with a pH of 4, and 100 times more acidic than a solution with a pH of 5.
