Acid-Base Properties of Salt Solutions:  Cu(NO3)2

An aqueous solution of Cu(NO3)2 will be acidic. The Cu2+ is the cation of a weak base (Cu(OH)2), thus it is an acidic ion and has an effect on the pH of the solution. The NO3- is from a strong acid (HNO3), thus it is a neutral ion. This compound in an aqueous solution will, therefore, form an acidic solution.
