WebPotassium bisulfate is a by-product in the production of nitric acid from potassium nitrate and sulfuric acid: KNO 3 + H 2 SO 4 → KHSO 4 + HNO 3 Chemical properties. Thermal decomposition of potassium bisulfate forms potassium pyrosulfate: 2 KHSO 4 → K 2 S 2 O 7 + H 2 O. Above 600 °C potassium pyrosulfate converts to potassium sulfate and ...
