acids and water
« on: June 15, 2011, 01:18:26 PM »
I am trying to work out the chemical equation of HNO2 + H2O and am getting confused as HNO2 is a weak acid and it doesn't dissociate fully. So presumably some stays in the solution but surely H2O needs to be in the 2nd part of the equation too. I also feel H+ and OH- needs to be aswell! Arghhh  thanks for any *delete me*

Acetic acid is very well discribed in books or the internet, with nitrous acid it is at least the same. You need the pKS value of the dissociation.

I guess you mean pKa. If I understand the situation correctly pKs is used in Germany only and will be not understood by most CF users.
