Potassium bisulphate and pyrosulphate are virtually identical in their behaviour, as may be seen from the equations showing their decomposition by heat:
2 KHSO4→ K2S2O7 + H2O
K2S2O7→ K2SO4 + SO3
In both cases sulphur trioxide is the effective attacking agent, acting in a medium of molten potassium sulphate.
