CAS number 10361-76-9
Molecular formula KHSO5
Molar mass 152.2 g/mol (614.76 as triple salt)
Appearance off-white Tablet and powder
Tablet Size:0.5g-5gram
Active Ingredient:5%
It is a component of a triple salt with the formula 2KHSO5·KHSO4·K2SO4.
Uses
Potassium peroxymonosulfate can be used in swimming pools to keep the water clear, thus allowing chlorine in pools to work to sanitize the water rather than clarify the water, resulting in less chlorine needed to keep pools clean. One of the drawbacks of using potassium peroxymonosulfate in pools is it can cause the common DPD #3 water test for combined chlorine to read incorrectly high.
