Acids produce solutions that Taste sour Turn litmus

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.

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.

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

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

• Red litmus paper • Blue litmus paper • p. H • Red Cabbage Juice

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

• 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.
