Balance the following redox reaction that occurs in a basic solution: N₂O₄(aq) + TeO₃²⁻(aq) → Te(s) + NO₃¹⁻(aq))
Substances A, B, and C can all act as oxidizing agents. In solution, A is green, B is yellow, and C is red. In the reactions in which they participate, they are reduced to A minus, B minus, and C minus ions, all of which are colorless. You are given an unknown, colorless, solution that contains one of the following salts: N a A, N a B, N a C. In solution, each salt dissociates completely into the Na+ ion and the anion A minus, B minus, or C minus. The N a + ion is effectively inert. You are given the availability of solutions of A, B, and C, develop a simple procedure for identifying the salt that is present in your unknown. Hint: For X2 + 2 Y 1 minus ---> Y2 + 2 X 1 minus If a reaction occurs, X is more active than Y. If a reaction does not occur, Y is more active than X.
