I have been trying to find the specific heat capacities from different books for 2 M of sodium hydroxide (NaOH), 2 M of hydrochloric acid (HCl), and 2 M of ammonium hydroxide (NH4OH); however, I have unfortunately been able to calculate these values properly from charts.  I believe the values will be close to that specific heat of water (4.184 J/g deg).  If anyone can point me in the right direction of acquiring these specific heat values, I would be most appreciative.

Just two quick google results. You have to convert units and interpolate (I would just assume that between 10% and 0% is linear and at 0% HCl it is the specific heat of water). I am sure you can find Ammonium Hydroxide. Though, if you have access to a Handbook of Chemistry (CRC, Langes, etc) it will have them all for sure. You might even have free access online through your schools library.

Thank you for your help.

Dear Bevswg04;

For HCl you may also use, for the range 1.0 %w/w till  16.8 %w/w:   

"Specific Heat capacity question (HCl)?”

The corresponding values in kJoule kg^-1 °K^-1 from the top are:  4.096;  4.037; 3.677; and 3.134.

Good Luck!

Dear Bevswg04;

Finally I found also for Ammonium Hydroxide (AH) values!

I found in a “little before yesterday” LANDOLT & BÖRNSTEIN:
(A standard “Book” for such properties.)

AH  +  100 H₂O (= 1.9%w/w = 0.542 molar)  at 18°C  = 4.180    kJoule kg^-1 °K^-1
AH  +    50 H₂O (= 3.7%w/w = 1.056 molar)  at 18°C  = 4.180           “
AH  +    30 H₂O (= 6.1%w/w = 1.743 molar)  at 18°C  = 4.171           “
(The same book up to date would give you much more!)

I hope it gives you not only an Idea.

Good Luck!
