Aluminum ion in solution reacts with water to form aqueous hexaaguaaluminum ()ion. Write this reaction below,...
Aluminum ion in solution reacts with water to form aqueous hexaaguaaluminum ()ion. Write this reaction below, remember phases. Aluminum is more likely to form a hydrated complex than the other four ions remaining in solution, because of its relatively small size and high charge To separate the Group B2 ion, the solution first is made basic by adding ammonia. In the presence of this weak base the pH is adjusted to 9-10 and the group B ions form insoluble hydroxides....

A buffer solution contains a mixture of aqueous ammonia, NH3(aq), and ammonium chloride NH4Cl(aq). A small amount of sodium hydroxide solution, NaOH(aq) is added. Which of the following correctly describes the buffering action occurring in this solution on mixing? A. Hydroxide ions are removed by reaction with NH3(aq) to give NH4OH (aq) B. Sodium ions are removed by reaction with Cl- to give NaCl C. The presence of NH3 (aq) prevents the NaOH from dissociating into ions D. Hydroxide ions...
