What is pH?
-when water disassociates, it yields a hy-
drogen ion and hydroxide molecule
-hydrogen ion concentration in pure wa-
ter at room temperature is about 7.0 and
considered "neutral" because the con-
centration of hydrogen (H=) and hydrox-
ide (OH-) ions are equal.
-acids are formed as waste products that
may need to be neutralized or eliminated
-normal metabolism produces more
acids than bases
-acid solutions have a sour taste and pro-
