Acids and Bases Mrs. Leos

Acids A substance that can donate a hydrogen ion to another substance Must contain hydrogen ion (H+) in a solution Properties: Sour taste Electrolytes Corrosive React with indicators Blue indicator paper turns pink

Examples of Acids Orange juice Tomatoes Vinegar

Common Acids: Acetic Acid- vinegar Ascorbic Acid- citrus, tomatoes, veggies Carbonic acid-carbonated drinks Hydrochloric Acid- gastric juice Nitric Acid- explosives Phosphoric acid-detergents Sulfuric Acid- car batteries

Bases A substance that can accept a hydrogen ion from another substance Must contain hydroxide ion (OH-) in a solution Properties: Bitter taste Feel slippery Corrosive Electrolytes React with indicators Pink indicator paper turns blue

Examples of bases Soap Ammonia Antacid

Common Bases Aluminum Hydroxide- deodorant Magnesium Hydroxide- antacid Sodium Hydroxide- drain cleaner Ammonia- household cleaners
