http://www.civil.northwestern.edu/EHE/COURSES/eac/exp2/res2.htm WebThe pH of the solution is equal to the negative logarithm of hydrogen ion (H +) concentration. pH = – log [H +] At pH value 7, the solution is neutral. In contrast, if the pH value is greater than 7, the solution will be alkaline, or if the ph value is less than 7, the solution will be acidic. Both Ka and pH are associated with each other.
