i want to know if it is possible to have a pH of 0.00 for any solution and why ?

Check what should be the concentration of H+ ions for the pH to be 0.0. If it seems reasonable, you can have solution with pH = 0.0.

-log[H+] + -log[OH-] is always 14.  and that 0.00 is possible, even -1.  A 1 M solution of HCL would yeild 0.00 pH and this is merely a measurement.  pH is not a naturally occuring item, it is designed to take rediculously hard to work with number like 1 x 10^-7 and make it a 7.  HOWEVER, you cannot have a concentration of H+ of 0.00 You cant have a pH too much lower than -1 feasably because even a strong acid takes up space, and you can only have so much acid in a 1L space.

Sidenote:  there are acids in solid form that can breakdown C60 and if that was on a pH scale that would be thousands of times stronger than HCL.  An acid is what you define it as.  and pH is only ONE way to view the picture.  when you say [H+] do you mean maybe H30+ or maybe H502+? there are many ways to express even the simplest of acids.  A good read would be to check out Dr Reed's webpage located at www.chem.ucr.edu under faculty and research.
