Solubility: The maximum amount of solute that can be dissolved in the solvent at equilibrium is defined as solubility.

Constant of soluble product: For equilibrium between solids and their respective ions in a solution, the solubility product constant is defined. In general, the term "solubility product" refers to water-equilibrium insoluble or slightly soluble ionic substances.

Considering the given information:

When all of the system's components are in their standard states, the standard free energy change ${\text{Δ³Ò}}^{\text{o}}$occurs.

The standard state is defined as $\text{1atm}$ for gases, 1M for solutes, and 1M for pure solids and liquids. The term "standard state" does not specify a temperature because it can occur at any temperature.

${\text{Δ³Ò}}^{\text{o}}=\text{Δ³Ò}$when all concentrations equal 1M and all partial pressures equal 1 atm.

This is due to the fact that the values of Q=1 and $\text{lnQ=0}$in the following equation,

${\text{Δ³Ò=Δ³Ò}}^{\text{o}}\text{+RTln(Q)}$

Where,

R is gas constant

T is the temperature

$\text{Δ³Ò}$is the free energy

${\mathbf{\text{Δ³Ò}}}^{\mathbf{\text{o}}}$is standard free energy.
