justified approximation

Postby inlovewithchemistry » Fri Mar 15, 2019 11:25 pm

when can you justify that it is okay to ignore the second ionization? what will be the indication that we dont have to do the second ionization?

I am not sure what you are referring to when you say second ionization but if you are referring to the second ionization for a diprotic or polyprotic acid we can, for the most part, ignore it because the amount of hydronium (H+1) produced from the first deprotonation is significantly greater than the amount produced from the second deptrotonation.
