Once a metal ion has become fully hydrated to become a metal hydrate, the resulting complex can exhibit behavior that is characteristic of a: Select the correct answer below:
strong acid
weak acid
strong base
weak base
Homework Answers
The resulting complex i.e.if a metal is fully hydrated, metal
hydrate is formed. The exact behavior of metal hydride depends on
type of M-H bond where M is metal and H is hydride and their
electronic properties.

Dissolution of the Precipitate-Basicity of the Anion Phosphate ion, the conjugate base of HPO is one example of an anion of a weak acid. In solution, we can expect phosphate to do two things: Accept an Hion, as well as form precipitates with metal cations such as Fe. These two reactions are shown below: PO. (ag) + H (ap) HPO. (ag) K, for (HPO ) = 4.8 x 10" FePO.(1) Fe (my) + PO. (a) K = 1.3 x 10"...
