A small sample of potassium sulfate could be prepared by (carefully) mixing a small amount of sulfuric acid with a small amount of potassium hydroxide and then evaporating the water off to leave the potassium sulfate. The two reactants should be measured carefully so that complete neutralization occurs without any remaing reactants, but this is a relatively easy way to make up the required compound. The acid and base react to form the salt and water in the classic manner.
