Sodium Halides and Sulphuric acid

Hi,

In the reaction between sodium halides with sulphuric acid, sodium hydrogensulphate is produced. Why would this be produced instead of sodium sulphate?

Is is because of lower energy require for this reaction compared to forming sodium sulphate?

Many thanks in advance,

It might be that the sulphuric acid has two hydrogen ions but can only donate one to create the hydrogenhalide, leaving one left as hydrogensulphate?
