+## pH
+ - Used as a scale to measure how acidic or basic a substance is
+ - Presented as a scale from 0-14
+ - The lower the pH the more acidic, the higher the pH the more basic
+ - Measures `concentration` of hydrogen ions in solution
+ - pH scale is logarithmic
+ - Concentration is increased tenfold when pH is increased by 1
+    - pH 1 = 0.1 mol/L
+    - pH 14 = 0.00000000000001 mol/L
+ - Water at 25 degrees Celsius is pH 7.0 (neither acidic nor basic)
