 # Solubility Equilibria of Sparingly Soluble Salts

The solubility depends on a number of factors important amongst which are the lattice enthalpy of the salt and the solvation enthalpy of the ions in a solution. For a salt to dissolve in a solvent the strong forces of attraction between its ions (lattice enthalpy) must be overcome by the ion-solvent interactions. The solvation Read more about Solubility Equilibria of Sparingly Soluble Salts[…] # Work Energy Theorem

Principle: The work-energy theorem is a generalized description of motion that states that the work done by the sum of all forces acting on an object is equal to the change in that object’s kinetic energy.f = ma f = m dv/dt We know that dw = fdx w = ∫ f. dx = ∫ m.

We know that if,  ΔG is negative, then the reaction is spontaneous and proceeds in the forward direction. ΔG is positive, then reaction is considered non-spontaneous. Instead, as reverse reaction would take place  ΔG is 0, reaction has achieved equilibrium; at this point, there is no longer any free energy left to drive the reaction.
