Problem

Consider the generic ionic compounds with the formulas A2X and BY2 and the following solubility rules:
A2X soluble; BY2 soluble; AY insoluble; BX soluble.
Assume A+ ions are circles, B2+ ions are squares, X2- ions are trianges, and Y- ions are diamonds. Solutions of the two compounds (A2X and BY2) can be represented as follows:

Two solutions, the solution on the left contains four red circles labeled A+, and two green triangles labeled X2-. The solution on the right contains two yellow squares labeled B2+ and two blue diamonds labeled X-.

Draw a molecular level representation showing the result of mixing the two solutions given.

Solution

We have to draw a molecular level representation of the reaction between A2X and BY2that produces AY and BX.


A2X + BY2→ 2 AY + BX

We have been given the information that AY is an insoluble compound while BX is soluble.

We know that soluble ionic compounds are present as their ions in the solution.
