Ph Scale Coirle Test the ph of everyday liquids such as coffee, spit, and soap to determine whether each is acidic, basic, or neutral. investigate how adding more of a liquid or diluting with water affects ph. A ph value is the quantitative measure of the acidity or basicity of aqueous or other liquid solutions. the term, widely used in chemistry, biology, and agronomy, translates the values of the concentration of the hydrogen ion into numbers between 0 and 14. Acid rain and the ph scalethe ph scale measures how acidic an object is. objects that are not very acidic are called basic. the scale has values ranging from zero (the most acidic) to 14 (the most basic). as you can see from the ph scale above, pure water has a ph value of 7. this value is considered neutral—neither acidic or basic. normal, clean rain has a ph value of between 5.0 and 5.5. Solutions are classified as acidic or basic based on their hydrogen ion concentration relative to pure water. acidic solutions have a higher h concentration than water (greater than 1 × 10 7 m), while basic (alkaline) solutions have a lower h concentration (less than 1 × 10 7 m).

Ph is a logarithmic scale. a solution that has a ph of 1.0 has 10 times the [h ] as a solution with a ph of 2.0, which in turn has 10 times the [h ] as a solution with a ph of 3.0 and so forth. a logarithm is a shorthand for expressing really big numbers and really small numbers. Use ph scale basics to test your ideas about some common things that are acids or bases. a. describe your tests and results. adding 0.11 l of water to 0.11 l of drain cleaner lowered its ph from 13 to 12.70. adding 0.11 l of water to 0.11 l of orange juice increased its ph from 3.5 to 3.8. Ph is a logarithmic scale. a solution that has a ph of 1.0 has 10 times the [h a ] as a solution with a ph of 2.0, which in turn has 10 times the [h a ] as a solution with a ph of 3.0 and so forth.
