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.
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.
[tex]pH=-\log [H^+][/tex]
[tex]pOH=-\log[OH^-][/tex]
Thus pH scale Is based on the concentration of hydrogen ions.
