Why is pH a negative logarithm?

[QUOTE="mfb, post: 6027340, member: 405866"] It is just more convenient as most numbers are between 0 and 14. You save a sign most of the time. There are acids strong enough to create a negative pH. There is nothing special about 1mole/l, as both mole and liters are arbitrary units. Water has about 55 mole per liter, once you have more than 0.02 H[sub]3[/sub]O[sup]+[/sup] molecule per water molecule the pH gets negative. From a modern point of view the fraction of molecules which are H[sub]3[/sub]O[sup]+[/sup] would be a more natural choice. [/QUOTE]
