Prediction: The Cucl, crystal will dissolve in water. If we write the solvation process as a chemical equation, we can predict two possible outcomes:
a. Cuci
H2O Cu?* (aq) + 2 Cl(aq)
H2O Cu2+ (aq) + Cl2(9)
+ 9
.
b. Cuciz
In equation (a) Cl' ions remain dissolved in water whereas in equation (b) the chlorine molecule CI,
forms and leaves the solution as a gas. Which outcome do you expect (a or b)? Explain your reasoning.
