ACIDS  taste sour  are corrosive to metals  change blue litmus to red  become less acidic when mixed with bases  release H +

BASES  feel slippery (denature protein)  change red litmus to blue  become less basic when mixed with acids  release OH -

 STRENGTH OF ACIDS › Depends on the:  concentration of ionized hydrogen  STRENGTH OF BASES › Depends on the:  completion of the ionization into OH - and a conjugate acid

 Through the pH values, using the pH meter.  If the pH value is greater than 7, it is basic.  If the pH value is lesser than 7, it is acidic.

pH INIDCATORS  help determine the pH of the solution visually  Help determine if the solution is acidic or basic

 Cleaning  Sanitizing  Cooking  Baking  Car batteries  Synthesizing other compounds
