A homogeneous solution of hydrated ions is initially observed, when a further 10 g of KCI is added, some of the added KCI is observed to dissolve, but some of the additional KCI remains in solid form. O b. A heterogenous system involving an equilibrium between hydrated KCI ions and solid KCI is observed. O c. A homogeneous solution of hydrated ions is initially observed, when a further 1 g of KCI is added, this additional KCI is also observed to dissolve. O d. A homogeneous solution of hydrated ions is observed before spontaneous crystallisation of KCl occurs when the solution is poured onto a crystal of KCI.
