The extent of a compound's dissolving is based on the thermodynamic quantities of enthalpy and entropy. The enthalpy of dissolvi
ng depends on the -Choose... the number of arrangement strength of attraction /other ions present- between the ions in the solid-state and between the ions and-Choose...the container/ the temperature/the solvent. The entropy of dissolving is usually thermodynamically -Choose... favored/ disfavored because the ions have -Choose...stronger attractions/more available arrangements/greater organization- when dissolved.
When a solute is dissolved in a solvent, the ions that have been trapped in the solid become free and the free ions increases the number of particles in solution thereby increasing the entropy of the system. Increase in entropy is favourable to dissolution. Entropy is defined as the degree of disorder in a system.
Dissolution also depends on the ability of solute to effectively interact with the solvent,that is, a enthalpy of dissolution.
