Well, I have been recently dissolving some salts into water using sonication technique (especially when the amount of solute is very high). I had the notion that by using sonication technique, the temperature increases due to which solubility increases. My question is some salts like cerium sulphate exhibit an unique behaviour. That is, their solubility decreases with increase in temperature. So can we dissolve Cerium sulphate into water using sonication technique? Or is my whole idea of how sonication can dissolve salts is itself wrong?
Do you mean cerium (III) or cerium (IV) sulfate?
For cerium (II) see
"So why does the solubility of cerium sulfate (green plot) diminish with temperature?" in

My question relates to any salt whose solubility decreases with increase in temperature. I just found out from internet, that cerium sulphate's solubility decreases with temperature. I guess you can assume any salt of your choice ( such that it's solubility decreases with temperature)
You can try first and see whats happened.BTW, why do you not choose nitrate source in stead of sulfate?
The sonication just increases the surface area of a solid material to be dissolved. To speed up the dissolution of cerium sulfate you may try to sonicate at lower temperature.
So Prof.Geletti is it like, when we perform sonication the solute particles are trapped within the bubble and due to cavitation and bubble destruction, the solute particles undergo size reduction?
as mentioned earlier solubility is a thermodynamic property, i.e. it does not depend on how you reached there. Supersaturation is a different thing.
