It depends on what the experiment is.
Often times you set as a null hypothesis a statement of what you want to disprove.
Then you run an experiment, the results of which you hope would only occur with a low probability give the null assumption was true. If the probability is very low, then you have a good reason to reject the null (which usually is what you wanted all along).

The Null hypothesis is the statement that you are proving false.
For example the null hypothesis could be that smoking has no correlation with lung cancer.
