ACIDS & BASES

Acids produce solutions that: Taste sour Turn litmus paper red Conduct electricity react with metals to free a hydrogen gas are corrosive (acid rain) lose the above properties when reacted with a base.

ACIDS Examples of acids: Vinegar Lemon Juice Soft Drink Battery Acid Stomach Acid Apple Juice Black Tea

Bases produce solutions that: taste bitter turn red litmus blue conduct electricity feel slippery are corrosive lose the above properties when reacted with an acid.

BASES Examples of bases: Detergent Baking Soda Drain Cleaner Ammonia Soaps (hand, dish) Antacid

NEUTRAL These are items that are neither acids nor bases. The main example of a neutral item is: Pure Water

DETERMINING ACIDS & BASES Red litmus paper Blue litmus paper pH Red Cabbage Juice

pH - the negative logarithm of the hydronium ion concentration of an aqueous solution; used to express acidity. pH is the measure of the acidity or basicity of a solution. The pH scale ranges from 1 to 14 1 through 6 being acidic 7 is considered neutral 8 through 14 being basic

IN YOUR BODY Proteins in your hair, nails, cell membranes, and other parts of you body consist of amino acids. Enzymes that catalyze reactions in your body are composed of amino acids. Hydrochloric acid is in your stomach to aid in the digestion of food. Organic bases are major components of DNA and products of the digestion of proteins.
