Heat capacity

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

More than you ever wanted to know about sodium hydroxide.

i can't find it on there? :confused:

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

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.
