Question

In both directions on the scale, between the whole number value, there is a difference of ____________ times the concentration of hydrogen ions and hydroxide ions. A pH of 5 is 100 times more acidic than a pH of 7.

Answer 1

10

Step-by-step explanation:

pH is described with a logarithmic scale, so you need to know that this scale grows exponentially, and for each whole number that you move on between all parts in the scale you will grow or decrease by a factor of 10. So the answer is 10 times the concentration of hydrogen ions and hydroxide ions.
