heat of neutralisation of formic acid with NaOH i at 298K is 56.07KJ?

Question

What is the heat of Ionisation of formic acid?

Answer 1

You can use Hess's Law to determine this, but you're going to have to look up the heat of ionization of water in a table or in a problem somewhere.

So, the reaction that you want the DH (D=delta) for is:

HCOOH --> H+ + HCOO-

You know DH for the reaction:
HCOOH + OH- --> H2O + HCOO-

If you can find DH for the reaction:
H2O --> H+ + OH-

Then you can add those last two equations, and what you're left with is the equation whose DH you are trying to find...

Answer 2

I think so it is same as 56.07kj bcoz if you use DE=DH+Dn(gas)RT then Dn=0 if formic acid is in Liquid phase

Answer 3

the 1st answer is actual for the neutralization of formic acid with sodium hydroxide. Formic acid is what a bee injects while it stings. putting baking soda NaHCO3 on a bee sting makes use of the reaction to neutralize the consequence of the area.

Answer 4

Maybe, look up a standard table.
