What phase is potassium iron?

Potassium iron is typically in the solid phase, as it forms a compound like potassium ferrate (K2FeO4) or iron potassium oxides (KFeO2).

Does potassium permanganate and copper sulphate undergo sublimation?

No, potassium permanganate and copper sulfate do not undergo sublimation. Sublimation is the process in which a substance transitions directly from a solid to a gas without passing through a liquid phase. Potassium permanganate and copper sulfate undergo a different process known as decomposition when heated.


Why is KI - potassium iodate - used in the determination of the partition coefficient?

Potassium iodate (KI) is used in the determination of the partition coefficient because it forms a colored complex with iodine, which allows for easy visual detection of the iodine in each phase. This helps in measuring the concentration of iodine in the two phases, which is essential for calculating the partition coefficient.


What evidence do you have that the equilibrium shifted when saturated potassium nitrate solution was cooled?

The evidence that the equilibrium shifted when a saturated potassium nitrate solution was cooled is the precipitation of potassium nitrate crystals. Cooling the solution causes a decrease in solubility, leading to excess solute (potassium nitrate) to precipitate out of the solution. This indicates that the equilibrium has shifted towards the solid phase as a result of the change in temperature.
