1. The problem statement, all variables and given/known data How would you separate a mixture of potassium sulfate and mercurous sulfate solids? Be sure to indicate how you got two separate solids. 2. Relevant equations 3. The attempt at a solution I know that the mercurous sulfate is insoluble, so my first thought would be to dissolve the potassium sulfate in water and that would sepererate them. However I could not think of how to return the dissolved potassium sulfate back to its solid form.
