-when equilibrium is established

-when the two phase system is saturated

I think the correct answers from the choices listed above are the third and fourth options. Ksp is determined for a system when equilibrium is established and the two phase system is saturated. Hope this answers the question. Have a  nice day.

Explanation:

\(K_{sp}\) is known as solubility product and it is defined as when a solid and its ions in a solution are in equilibrium with each each other.

Therefore, in order to determine the \(K_{sp}\) of a reaction equilibrium has to be established.

Also, the two phase system has to be saturated because saturation makes the rate of dissolving equal to the rate of precipitation.

            Rate of dissolving = rate of precipitation

Therefore, this helps in the establishment of equilibrium.

Hence, we can conclude that \(K_{sp}\) can be determined for a system:

  • when equilibrium is established
  • when the two phase system is saturated
