The pKa of acetic acid is 4 75 The pKa of ammonia is 9 3 The pKb of acetic acid is 9 25 The pKb of ammonia is 4 7 Acetic acid is a strong acid than the conjugate base of ammonia Ammonia is a stronger base than the conjugate base of acetic acid
Test2 ch17a Acid-Base Practice Problems
e the more concentrated the conjugate base c the more concentrated the acid 11 Ammonia (NH 3) acts as a weak base in aqueous solution What is the acid that reacts with this base when ammonia is dissolved in water? a none, there are no acids in pure water b H 2O c NH 4 + d trick question, because no acids are present, ammonia cannot

Examples of common bases include soap, ammonia, and bleach Milk of magnesia is a mild base people drink to cure an upset stomach The strength of an acid or base is measured on the pH scale The scale ranges from 0–14 A pH value between 0 and 7 means the substance is an acid A pH value between 7 and 14 means the substance is a base
