5. The Reactants with Aqueous Ammonia Acid-Base: NH 4 OH (aq) + HCl (aq) → NH 4 Cl (aq) + H 2 O (l) In this acid-base reaction, as in all of the acid-base reactions, the resulting solution is acidic. There is no visible change in the reaction. Gas-Formation: 2NH 4 OH (aq) + BaCl 2(aq) → Ba(OH) 2(aq) + 2NH 4 Cl (aq) The reaction neutral barium chloride with basic ammonium nitrate results in a neutral solution.

Unformatted text preview: There is no visible change in the reaction. Complex-Ion Formation: 2NH 4 OH (aq) + Co(NO 3 ) 2 ∙ (aq) → 2NH 4 NO 3(aq) + Co(OH) 2(s) The reaction of acidic cobalt (II) nitrate and basic ammonium nitrate results in an acidic solution. A precipitate forms resulting in visible cloudiness because an insoluble metal is part of a reactant....
