pH scale is
used to describe the acidity of any solutions.
pH is a
measure of how acidic is a basic or acid.
The scale
ranges from 0 to 14, with acid solutions having a pH value less than 7 and
basic solution, greater than 7. Very acidic solutions have a low pH and very
basic have a great pH. A neutral solution, like pure water, has a pH of 7.
pH is a
logarithmic scale meaning that one unit on the scale equivalent a ten fold
change in concentration.
-
pH of
3 is 10 times more acidic than a pH of 4
-
pH of
10 is 100 times less acidic than a ph of 12
