Bases are substances that increase the hydroxide ion concentration in aqueous solution.Why does ammonia (NH₃),which does not contain a hydroxide group,act as a base? A)Ammonia acts as a base only in the presence of hydroxide ion-containing compounds B)Ammonia molecules remove protons from water molecules,forming hydroxide ions C)Ammonia molecules donate protons to water molecules,forming hydroxide ions D)Ammonia acts as a base only in the presence of very strong acids

Question

Even though ammonia does not contain a hydroxide group, it can act as a base by accepting a proton from a water molecule to form an ammonium ion (NH4+) and a hydroxide ion (OH-). Therefore, the presence of ammonia in aqueous solution can lead to an increase in the concentration of hydroxide ions.
