Solutions and pH.

PH is the measurement of the concentration of H+ ions in a solution. (Or how acidic or basic a solution is.) 1. The pH scale has a range from 1 to 14.

 The pH scale measures the acidity of a substance.  p = potential  H = Hydrogen ions (H + ) in a water solution  What is an ion? ______________________________________.

Can you group the following solutions?

How can solutions be classified? ACIDS NEUTRAL BASES

AAAAAAA N BBBBBBB Acid Neutral Base pH 0 - 6 pH 7 pH 8 - 14 Most acidic Most basic Acid Neutral Base pH 0 - 6 pH 7 pH 8 - 14

Acids vs Base Acids have pH below 7 because they have more H+ ions than OH- ions. Acids have more H+ Bases have pH above 7 because they have more OH-

What is the pH of your body? pH of fluids in most cells in the human body must generally be kept between 6.5 and 7.5 Too high or too low will affect chemical reactions that take place within the cells.

The action of enzymes varies with pH What is the optimum pH in the stomach. What is the optimum pH in the intestine. What does the term “range” mean?
