1.Ammonia forms the complex ion [Cu(NH3)4]2+[Cu(NH_3)_4]^{2+}[Cu(NH3)4]2+ with copper ions in alkaline solutions but not in acidic solutions. What is the reason for it?a.In acidic solutions protons coordinate with ammonia molecules forming NH4+NH_4^+NH4+ ions and NH3NH_3NH3 molecules are not available.b.In alkaline solutions insoluble Cu(OH)2Cu(OH)_2Cu(OH)2 is precipitated which is soluble in excess of any alkali.c.Copper hydroxide is an amphoteric substance.d.In acidic solutions hydration protects copper ions.Login to continueOnly logged in users canattempt or see the solution.
