?An aqueous solution of a cation (represented as blue spheres in the diagram) is allowed
Chapter 5, Problem 5.20(choose chapter or problem)
An aqueous solution of a cation (represented as blue spheres in the diagram) is allowed to mix with a solution of an anion (represented as green spheres) and the following result is obtained:
Which combinations of cation and anion, chosen from the following lists, are compatible with the observed results? Explain.
Cations: \(\mathrm{Na}^{+}, \mathrm{Ca}^{2+}, \mathrm{Ag}^{+}, \mathrm{Ni}^{2+}\)
Anions: \(\mathrm{Cl}^{-}, \mathrm{CO}_{3}^{2-}, \mathrm{CrO}_{4}^{2-}, \mathrm{NO}_{3}^{-}\)
Text Transcription:
Na^2, Ca^2+, Ag+, Ni^2+
CO^-, CO_3^2-, CrO_4^2-, NO_3^-
