Question

You are given potassium carbonate solid and potassium sulfate. Both are white solids. How would you separate potassium carbonate and potassium sulfate?

Answer 1

Add water, dissolve the K2SO4, filter, the K2CO3 solid will not go through the filter paper. Dry the paper to recover the K2CO3. Evaporate the water from the filtrate to recover the K2SO4.
