Autoprotolysis

Postby claudia_1h » Tue Jan 21, 2020 9:53 pm

Can someone please explain when to not use the concentration of H+ to calculate pH? It's something about the dissociation due to the autoprotolysis of water but I don't remember the exact threshold...

If [H3O+] < 10^-7, then the solution is considered neutral because we know that autoprotolysis generates 10^-7 M H3O+
