Heat of Solution Database - Calcium Chloride & Sodium Bicarbonate

[Draco]

You guys wouldn't happen to know where I can find a database or something that tells me the "Heat of Solution" for different compounds. In my assignment it tells me to "look up" the heat of solution for Calcium Chloride and Sodium Bicarbonate... Like I can't even calculate it since they don't give me anything to work with. It just tells me to look them up. Could you guys help me out?

CRC Handbook of Chemistry and Physics
ps. It's one of those offline paper things in the building with lots of offline paper things in.

What exactly is that? Everywhere I go people mention that. Don't I have to have an account of something to receive access?

 

[mgb_phys]

It's a brick size and weight reference for every physics/chemistty number you will ever need. It's also very useful for supporting lab equipement and killing insects.
I don't think it's available online (unless your school has some sort of deal)

It's been out for about 100 editions but doesn't change much (when did the atomic mass of Sodium last change?) so it's worth picking up old editions from junk stores.

oo ok. Thanks for the info, but I really only need the Heat of Solution and solubilities for Calcium Chloride and Sodium Bicarbonate now.

Then try http://webbook.nist.gov/chemistry/name-ser.html

Thanks but i don't see anything about heat of solution there :S

 

[mgb_phys]

Calcium chloride is there http://webbook.nist.gov/cgi/cbook.cgi?ID=C10043524&Units=SI&Mask=2#Thermo-Condensed
Oddly Sodium bicarb doesn't list any physical data.

ps it's also more properly called Enthalpy of Fusion - happy googling.

Thanks for the help :P, but i just need one more thing. You wouldn't happen to know where I could find the acid dissociation constant, and base dissociation constant of a bicarbonate ion would you? (K_a, and K_b) Sorry, but these assignment didn't have any instructions and it just told us to research it but I looked for hours and hours yesterday and didn't find a thing...

 

[mgb_phys]

There are a few links on the wiki page but you probably already checked those
http://en.wikipedia.org/wiki/Acid_dissociation_constant

 

[Draco]

There's nothing for a bicarbonate ion :(

EDIT: um nvm, don't worry about it. Thanks again. I just happened to find it in my textbook:P Thanks for the help :P
