7. (Calculator needed) In chemistry, the pH of a solution is the measure of the acidity of the solution. The definition for pH involves common logarithms: pH = -log[H+] where [H+] is the concentration of the hydrogen ion in moles per liter. The range for pH is from 0 to 14. Pure water, a neutral solution, has a pH of 7. An acidic solution, such as vinegar, will have a pH less than 7, and an alkaline solution, such as ammonia, has a pH above 7.
