The extent of a compound's dissolving is based on the thermodynamic quantities of enthalpy and entropy. The enthalpy of dissolving 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.

The enthalpy of dissolution depends on the strength of attraction between

the ions in the solid-state and between the ions in the the solvent.

The entropy of dissolving is usually thermodynamically favored  because

the ions have more available arrangements

A solution comprises of the solute and the solvent. The heat change which

takes place during dissolution is dependent on the strength of attraction

between the ions in the solute and solvent.

The entropy(degree of randomness) during dissolution is based on the

temperature changes because there is more arrangements of the ions

during collision of particles.

1)strength of attraction

2)the solvent.

3) favored

4)more available arrangements

Explanation:

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.
