Answer is: The pH scale is based on the concentration of hydrogen ions in a solution.

pH (potential of hydrogen) is a numeric scale used to specify the acidity or basicity an aqueous solution.

When pH is below 7, solution is acidic, pH greater that 7 solution is basic and pH equals to 7, solution is neutral.

Answer: The pH scale Is based on the concentration of hydrogen ions.

Step-by-step explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration.

Acids have pH ranging from 1 to 6.9, bases have pH ranging from 7.1 to 14 and neutral solutions have pH equal to 7. Thus pH scale range from 1 to 14.

$pH=-\log [H^+]$

$pOH=-\log[OH^-]$

Thus pH scale Is based on the concentration of hydrogen ions.
