Acids, Bases and pH,Part One,What is pH?,A measure of Hydronium Ion (H3O+) concentration in solution Measured on a scale ranging from 0 14 Acid = 7 Neutral = 7, example: pure water,What is an Acid?,A substance that produces hydrogen ions (H+) in solution Acids have a pH less than 7 The further away from seven the stronger the acid Example: A pH of 2 is more acidic than a pH of 5,What is a Base?,A substance that produces hydroxide ions (OH-) in solution. Bases have a pH 7 The further away from 7 the stronger the base Example: A pH of 13 is more basic than a pH of 8,Examples of Common Acids and Bases,Acetic Acid Vinegar Acetylsalicylic Acid Aspirin Hydrochloric Acid Gastric juice in the stomach Aluminum Hydroxide Deodorant Sodium Hydroxide Drain cleaner, soap making Ammonia Household cleaners,
