Acids are corrosive when concentrated and taste sour. Bases, like acids, can be corrosive, and taste bitter (not sour). Acids contain hydrogen ions and Bases contain hydroxide ions. Acids and Bases are measured on the pH scale. Acids are measured from 0 to 7, bases are measured from 7 to 14, and anything with a pH of 7 is neutral. When testing for the pH of a substance, the indicator paper will turn more red if its acidic, and more blue if its basic.
