Complete the sentence. the lower the hydrogen ion concentration, the the ph. a. higher b. lower c. closer to 7 d. closer to 0

The lower the hydrogen ion concentration, the higher the pH, closer to 0.

Option (A) is the correct answer.

Explanation:

The relation between pH and hydrogen ion concentration is as follows.

                             pH =

When pH ranges between 1 to 6.9 then the solution is acidic in nature.

When pH is equal to 7 then solution is 7.

When pH ranges between 7.1 to 14 then the solution is basic in nature.

Hence, when there occurs a decrease in the concentration of ions. Then there will be an increase in pH of the solution.

Thus, we can conclude that the lower the hydrogen ion concentration, the higher the pH.

the volume increases
