equilibrium constant at elevated temperatures (up to 400C)
« on: July 08, 2019, 12:58:25 AM »
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
