A question on extracting professional knowledge
Thread Content
Adding the solute component A to the B-S partially miscible system will decrease the solubility of B in S________. By appropriately lowering the operating temperature, the miscibility of B-S ________. A increases B decreases C remains unchanged D uncertain. How should this question be analyzed? I hope someone experienced can help answer it. Thank you
Adding the solute component A to a B-S partially miscible system will reduce the solubility of B in S. By appropriately reducing the operating temperature, the solubility of B in B-S decreases
Just imagine the solubility curve: as A increases, the two-phase region gradually shrinks, and eventually, at the critical miscibility point, no separation occurs and the mutual solubility is at its maximum. 2 Lowering the temperature is unfavorable for dissolution, so the mutual solubility decreases
According to the triangular phase diagram, upon adding component A, the solubility curve shifts in the direction of point A, and the mutual solubility of B and S decreases; as the temperature drops, the solubility also decreases!
