And so the hydrogen, one of these hydrogens will basically be much more likely to dissociate from that oxygen. So water bind onto the metal zinc atom. The partially negative charge of oxygen is attracted to the positive charge of the zinc. And this decreases the ability of water to actually hold on to one of those H plus ions. And this is precisely what facilitates this process the dissociation of the H from this oxygen to basically form this molecule here. And this is because the PTA value is lowered from 15.7 to 7.0.
