pH of acidic ions

Postby Crystal Odipo 1F » Wed Dec 09, 2020 3:34 pm

In the example, of HCI +NH3 -> NH4Cl why does the CLE-not affect the pH?

This is because Cl- does not have a strong enough attractive force to break apart H2O molecules into H+ and OH-, so essentially you just have Cl- ions floating around in the solution being attracted to the H2O but not breaking any bonds.

The NH4Cl disassociates and then the NH4+ turns into an NH3 and an H+. The Cl- doesn't do anything else in the solution because there being nothing for it to bond to. pH is only influenced by [H+] so the Cl- doesn't matter.
