2 What does pH stand for? potential Hydrogen Refers to the substance’s ability to attract Hydrogen atoms
3 The pH Scale A series of numbers from 1 to 14. Used to describe how acidic or basic a solution is.Most acidic substances are at the low end of the scale.Most basic substances are at the high end of the scale.
4 pH Indicator PaperYou can find the pH of a solution by using indicator paper or an indicator solution.Indicator paper/solution turns a different color for each pH value.Matching the color of the paper/solution with the colors on the scale tells how acidic or basic a solution is.
5 Neutral pHA solution with a pH of 7 is neutral. This means that the solution is neither acidic nor basic.Example: Pure water has a pH of 7.
6 Basic pH Basic solutions have a pH greater than 7. High ability to attract Hydrogen ions.Example: Soap has a pH of 10.
7 Acidic pH Solutions with a pH less than 7 are acidic. Low ability to attract Hydrogen ions.Example: Lemons have a pH of 2.
