1.) Explain the similarity between Mg(OH)2 and Zn(OH)2 in particular why would any insoluble hydroxide tend to dissolve in an acidic solution?

Question

Are they both bases?

2.) Explain the difference in particular how does Mg^+2 appear to form complex ions with OH^- and NH3? If these complex ions form what would you observe?

Would you observe a solid or precipitate?

Answer 1

I need some help. What do you not understand about these questions? Both are bases and Mg(OH)2 does not form complex ions.
