Answer:
CaCl3 does not exist, it is an impossible molecular formula.
But if it were possible, then it would have been a salt, definitely soluble in water and it might possibly be hydrated in crystallised solid form with 2 molecules of H2O, if that is what you've meant by 'aqueous.
However if you meant CaCl2: this is soluble salt (Calcium chloride) of which also mono-, di-, tetra-, and hexa-hydrates exist.
