A substance that has a pH of 5 is 100 times less acidic than a substance of pH 3. An increase in a unit of pH is equivalent to a 10 fold decrease in the concentration of hydrogen ions.
As pH<7 is acidic, pH=7 is neutral and Ph>7 is basic, make a wild guess.
hint: use common sense or Google.
100
7 is considered neutral. Anything below that is acidic and anything above that is basic. 1 being the most acidic and 14 being the most basic. I think most people would consider something "acidic" until it is about 5pH or anything "basic" until about 9pH. However, saying something that is 6.9pH is slightly acidic is technically correct. http://www.ec.gc.ca/WATER/images/manage/qual/a3p7e-sm-rev.gif
