Match each solubility phenomenon or term on the left with its correct thermodynamic or practical description on the right. Which pair correctly connects each term to its appropriate description?
- Fractional crystallizationSeparation technique utilizing differences in solute solubilities across varying temperatures.
- Endothermic dissolutionProcess where heat is absorbed during dissolving, causing solubility to increase with rising temperature.
- Exothermic dissolutionProcess where heat is evolved during dissolving, causing solubility to decrease as temperature rises.
- Supersaturated solutionUnstable solution holding more dissolved solute than its normal equilibrium saturation limit at a given temperature.
Cevap
Fractional crystallization pairs with separation technique using solubility differences; Endothermic dissolution pairs with heat absorption increasing solubility with temperature; Exothermic dissolution pairs with heat evolution decreasing solubility with temperature; Supersaturated solution pairs with holding excess dissolved solute beyond equilibrium limit.
Each term directly aligns with its fundamental thermodynamic property or chemical application. Fractional crystallization isolates salts using temperature-dependent solubility variations; endothermic dissolution absorbs heat so solubility increases with temperature; exothermic dissolution gives off heat so solubility decreases with temperature; and a supersaturated solution holds excess dissolved solute beyond standard equilibrium capacity.
