Expert Solution
Step 1
pH is the negative logarithm of the hydrogen ion concentration. It is a measure of acidity or alkalinity in a solution. The acidic solution will have the greater concentration of hydrogen ions and lower the pH. pH ranges from 0 to 14. pH upto 6 is acidic, pH7 is neutral after 7, the pH is basic.
