Hi,

does anyone have references for equilibrium constants for:                                     

NaSO4 = Na^++SO_4^(-2)                                           
KSO4 = Na^++SO_4^(-2)                                                 
KCl= K^++Cl^-                                             
CaCL= Ca^(+2)+Cl^-       
CaCL2 = Ca^(+2)+2Cl^-

I am looking for some data idealy from 100C to 400C

anyone can help?

cheers,
Lucjan

There is no such thing as NaSO₄, KSO₄ or CaCl, so good luck searching for those.

Shall that equilibrium happen in a solvent, and then which one? At least pure water doesn't exist liquid above +374°C, and below that temperature, it needs much pressure.

well.. KSO4− in the form of ion pairs, in a suitably concentrated potassium sulfate solution. But, of course, such ion pairs are easily dissociated. etc.

I am talking about solutions under high pressure.

we are talking about water
