This property ensures complete separation when dividing hydroxides of group III cations because it causes Zinc 2+ and Aluminum 3+ to immediately redissolve into NaOH. Isoelectric focusing can be used to separate molecules with this property, such as proteins, by applying a potential difference across a pH gradient and allowing the small molecules to move towards the anode or cathode. One notable compound displaying it reacts with ammonia to form

Isoelectric focusing can be used to separate molecules with this property, such as proteins, by applying a potential difference across a pH gradient and allowing the small molecules to move towards the anode or cathode. One notable compound displaying it reacts with ammonia to form a hydroxide ion and with hydrogen choride to form a hydronium ion. FTP, name this property of substances such as water that can react as either acids or bases.
