pH Scale

• pH is a measure of how acidic or basic a solution is.
• The pH scale ranges from 0 to 14.
• Acidic solutions have pH values below 7
• A solution with a pH of 0 is very acidic.
• A solution with a pH of 7 is neutral.
• Pure water has a pH of 7.
• Basic solutions have pH values above 7.
• A change of 1 pH unit represents a tenfold change in the acidity of the solution.
•  For example, if one solution has a pH of 1 and a second solution has a pH of 2, the first solution is not twice as acidic as the second—it is ten times more acidic
