Whats the heat capacity of NaOH I can't find it anywhere?

AI Thread Summary
The discussion revolves around finding the heat capacity of sodium hydroxide (NaOH), specifically in its solid form versus as a solution. A user seeks this information to calculate heat generation using the formula q=mc(delta)t. Clarification is requested on whether the user is referring to solid NaOH or a solution. It is noted that for a sodium hydroxide solution, the heat capacity can be approximated to that of water, which is 4.2 J/K-gm. The conversation highlights the importance of providing relevant answers and avoiding dismissive responses that suggest users search for information themselves. Additionally, references to reputable sources, such as DOW and Perry's Handbook of Chemical Engineering, are recommended for accurate chemical data. It is emphasized that the density of a sodium hydroxide solution varies and is not equivalent to that of water unless it is very dilute.

Chemistry news on Phys.org
i can't find it on there? :confused:

You are working with solid NaOH (not solution) ?! :eek:

Why do you need the heat capacity ?

I need to calculate heat generated so I'm using this formula:
q=mc(delta)t
and i need c

How is the heat to be generated?

You didn't answer my (implied) question.

Are you talking about solid NaOH or a solution ?

If it is a sodium hydroxide solution, you can assume the heat capacity is equal to that of water (=4.2 J/K-gm).
 
it was a solution.

I asked the teacher and got it thanks everyone
 
Review this thread. This is a serious impediment to forums. Several replies have nothing to do with the answer.

NOTE:

Requests for clarification are always valid.

A DUMP answer is where you tell someone to Google it or Wikipedia it. They have probably have already done this and that is why their asking here.

The DOW reference is good because they make Sodium Hydroxide. A good library reference on chemicals is Perry's Handbook of Chemical Engineering. It has a table of Sodium Hydroxide heat capacities for solutions.

And NO, the density of a solution is NOT the same as water unless it is very dilute.
