Ph values less than 7 acid or base

WebThe pH scale is used to classify substances as acids and bases. The scale goes from 0 to 14. Things that are acids have a pH number that is less than 7. The lower the number, the stronger the acid. Bases have pH values higher than 7. The higher the number, the stronger the base. An example of a strong base is drain cleaner or oven cleaner. WebIf [H+] > 10-7, pH is less than 7 and the solution is acidic. If [H+] = 10-7, pH is 7 and the solution is neutral. If [H+] < 10-7, pH is more than 7 and the solution is basic. Importance …
