Good day.

I'd like to know if hydrated forms of chemicals are used in PPS mixes. In sample, MS uses MgSO4+7H2O, but formulation refers to MgSO4 only. I also doubt about other components of mixes - are they in hydrated form, and if yes, than how many H2O they must have?

Hmm... misunderstanding, I'm novice in English language. ;(

In Your receipt of MS, MgSO4 should be used or MgSO4+7H2O? I found (Your forum talks and my math calculations) that hydrated form of MgSO4 should be used, but in receipt used only MgSO4.

I have CaCl2+6H2O, but CaCl2+2H2O exists too, and I don't know exaclty how many CaCl2 I should use - MgSO4+7H2O issue confuses me.

I'd like to say that Your recipt is not clear, and can be misread. Can You write full chemicals formulas with H2O where required?


Or am I don't understand something?

K2SO4 Potassium sulfate
KNO3 Potassium nitrate
KH2PO4 Monopotassium phosphate
MgSO4.7H2O Magnesium sulfate heptahydrate
CaCl2.2H2O Calcium chloride dehydrate
(CaSO4)2.H2O Calcium sulfate hemihydrate

Thank You!
