Homework Answers
The solution is removed by decanting from crystals because the solution have water soluble impurities which were present in the raw material before crystallisation.
So to avoid those water soluble impurities, solution is removed.

It is desired to produce 1000 kg/h of Na_3 PO_4.12H_2 O crystals from a feed solution containing 5.6 wt % Na_3 PO_4 and traces of impurity. The original solution is first evaporated in an evaporator to a 35 wt % Na_3 PO_4 solution and then cooled to 293 K in a crystallizer, where the hydrated crystals and a mother-liquor solution are removed. One out of every 10 kg of mother liquor is discarded to waste to get rid of the...

Crystallization and Recycle. It is desired to produce 1000 kg/h of Na,PO, 12H2O crystals from a feed solution containing 5.6 wt % Na,PO4 and traces of impurity. The original solution is first evaporated in an evaporator to a 35 wt% Na3PO solution and then cooled to 293 K in a crystallizer, where the hydrated crystals and a mother liquor solution are removed. One out of every 10 kg of mother liquor is discarded to waste to get rid of the...

In this experiment, 0.070 g of caffeine is dissolved in 4.0 ml of water. The caffeine is extracted for the aqueous solution 3 times with 2.0 ml portions of methylene chloride. The methylene chloride extracts are combined and the solvent evaporated resulting in isolated caffeine crystals. Briefly explain why caffeine will prefer the methylene chloride solvent to the water solvent. You need to draw the structures for all three compounds.

3. Crystallization begins with a process called nucleation, where particles of the substance dissolved in solution begin to aggregate. Crystals then begin to form on these aggregates. Based on this, explain why Steps 3 and 4 in Part III may induce crystallization. Part II: Observations Upuy Describe qualitative changes to solution - Solution went from bright yellow, orange to a mare dacu Orange /ced - hydrogen peroxide is originally clear but tuck's oldcu in the solution. The addition of hydrogen...
