I'm going to do a lab activity but I am lacking Potassium Sulfate. It's a lab about mixing solution and watching the product precipitate.The chemical equation is this.
Ba(NO₃)₂(aq) + K₂SO₄(aq) --> BaSO₄(s )+KNO₃(aq). What can I use to replace
K₂SO₄? I'll see if there are some of the chemical substance that are suggested here left and use it instead.Thanks!

You can use any other Sulfate instead to precipitate Bariumions.

Laboratory (diluted) H₂SO₄ also works.
