An acid is a substance that produces 
    hydrogen ions in a water solution. 
   The ability to produce ions is what 
    gives their characteristic properties. 
   When an acid dissolves in water, H⁺ 
    ions interact with water molecules to 
    form H₃0⁺ ions, which are called 
    hydronium ions.
   Properties of Acids
   Citric Acid is found in citrus fruits.
   Lactic Acid is found in yogurt and 
    buttermilk.
   Vinegar is also known as acetic acid.
   Your stomach uses hydrochloric acid 
    to help you digest your food.

      Common Acids
   A substance that forms hydroxide 
    ions, OH⁻, in a water solution is a 
    base. 
   A base is also any solution that 
    accepts H⁺ from acids. 
   Think of bases as the opposite of 
    acids. 
   Properties of Bases
   In pure and undissolved state many bases 
    are crystalline solids.
   In a solution bases feel slippery and have 
    a bitter taste.
   Strong bases are like strong acids as they 
    are corrosive and can burn the skin.
