Hi,

Can someone explain how to calculate the standard enthalpy and entropy of aqueous acid solutions--say at 1 molar. 

I know these values are published for common mineral acids like HCl, but if you look at sources like NISTWebbook, only the gaseous values for these acid are published. 

I assume there is some way to calculate it from the thermodynamic properties of the ions in the resulting solution because these values seem available.

Thanks for any help.

they should be in the CRC handbook of physics and chemistry because that's where i would check first

So you can't calculate with NIST Webbook data?

i've never used that before. if you can find it with that, you should be able to. you just need to look for the enthalpy of solution under standard conditions. its a phase transition so it should be under enthalpy of transitions
