Why is CaSO4 (calcium sulphate) not soluble in hot water but soluble in cold water?
Can you explain to me why is CaSO4 not soluble in hot water but soluble in cold water?
Sure, CaSO4 has a solubility curve that shows it becomes less soluble as temperature increases. This means that at higher temperatures, the amount of CaSO4 that can dissolve in water becomes lower.
