Chemistry: Solubility

Question

I'm having issues writing an equation with the following information. Please help.

Beaker A contains: K+ and NO3

Beaker B contains: NH4 and Br-

Beaker A and B are mixed.

A.) If an insoluble salt forms, write the ionic equation.

B.) If a reaction occurs, write the net ionic equation.

Answer 1

So, just write the ionic forms of A and B together as follows:

K⁺(aq) + NO₃^-(aq) + NH₄⁺(aq) + Br^-(aq) ... after mixing A and B

You can see that all reactants are aqueous, and any products that could possibly form would also be aqueous. That is, you could form KBr and NH₄NO₃, both of which are soluble (aq), or you could reform KNO₃ and NH₄Br, also all soluble.

Thus, THERE IS NO PRECIPITATE AND NO REACTION. So, there is no net ionic equation.
