Rain naturally has a pH between 5 and 6. The pH of rain in parts of the U. This is acid rain. Living organisms are very sensitive to the effects of acids and bases in their environment. Thus, in order to maintain homeostasis and survive, organisms must maintain a stable internal pH. A buffer is a solution whose pH resists change on addition of small amounts of either an acid or a base. If the pH changes only slightly, the solution is a good buffer.

Eventually its buffering capacity will be exhausted, however, and the pH will change dramatically. Materials and Equipment. Exercise appropriate caution when using the Bunsen burner.

Procedure Materials and Equipment mL beaker, ring stand, wire gauze, Bunsen burner, large test tubes, dropper pipet, stirring rod, wash bottle with distilled water, laboratory pH meter, 0.

Add about mL of distilled water to this beaker. Make sure that all of the leaf pieces are completely submerged. Gently boil the mixture on heating plate until it appears dark purple in color min. Turn off the heat and allow to cool 5 min. Add cabbage indicator solution to pH standard solutions, labeled Students will record the colors of the pH standards.

Label each test tube with the solutions to be tested. Pour about 3-mL of each solution into the appropriately labeled test tube. Can You Have Negative pH?

The H must be capitalized because the first letter of abbreviations for chemical elements in this case Hydrogen are always capitalized. Examples would be Ni for nickel, O for Oxygen, etc. In the scientific world, p has come to refer to the inverse logarithm of the concentration of an element, so people now refer to pOH as -log[OH] , when in reality this means "puissance d'hydroxide" the brackets mean concentration, or amount per volume, OH is hydroxide, the ion which combines with H to form water, HOH or H 2 O.

The 'H' in pH refers to the concentration of hydrogen ions in a solution.
