Does ferric chloride and calcium chloride mix?

Yes, ferric chloride (FeCl₃) and calcium chloride (CaCl₂) can mix in solution. Both compounds are soluble in water and will dissociate into their respective ions when dissolved. However, mixing these two salts may lead to the formation of precipitates or changes in solution properties depending on the concentrations and specific conditions. It's essential to consider the intended application and potential reactions when combining these chemicals.
