How is a supersaturated solution prepared
WebFinal answer. 2) When a supersaturated solution of sodium acetate (NaCH3COO) has a sodium acetate crystal dropped into the solution, the solution quickly turns into sodium acetate trihydrate (NaCH3COO ⋅3H2O) which is a solid crystal. If NaCHH3COO(aq)ΔHf = −709.32 kJ/mol, H2O(ℓ)ΔHf = −285.8 kJ/mol, and NaCH3COO⋅ 3H2O(s)ΔHf = −1604 ... WebDescribe the difference between saturated, unsaturated, and supersaturated solutions. 10.
