Another pH question

[MaximumTaco]

Is it really possible to have strong acid/bases with a negative pH in practice, or is it purely theoretical. Like we say 10M HCl has pH = -1, does it really?

Is there something that limits the range of possible pH values for a solution?

[wolfson_1123]

Yes it is possible and does happen, just browse yahoo and look up "superacids", you can easily have a negative pH of -1. And there are NO limits for a pH value.

There is a law called Ostwald's dilution principle, and it states that pH is within 0 and 14 for solutions obeying this law. The response for pH with respect to concentration is somewhat deviated in very dilute and concentrated solutions.
