You asked this question on Wednesday, and got an answer. Googling 
sulfate gromacs finds that answer. If you learn to make better use of 
the free information resources at your finger tips, then you will 
probably find that people will be more inclined to help you later on 
when the answer to that problem is not a simple web search away. Our 
time is valuable to us, too :-)

That depends on the force field you want to use.  There are parameters for 
sulfate in all of the Gromos force fields, but I can't comment on their 
suitability.  You should also not just pick one of these because it happens to 
already exist in order to make your life easy.


Check the literature for suitable parameters, otherwise have a look at 
http://www.gromacs.org/Documentation/How-tos/Parameterization and be prepared 
for a lot of work.

Thanks alot
