Chlorine Concentrations

[global92]

Greetings to all on the forum.
I am a newbie and there are some really interesting topics under disussion.
I am wondering if anyone can help me with my particular challenge?
I have to make up a 3% chlorine solution to dose a well with.
My base starting material is granular calcium hypochlorite with 650gms/Kg of available chlorine.
I intend to start with a 65% solution and dilute from down from there to 3%. this I do know how to do.
What I dont know is how many grams of calcium hypo I have to add to 1 litre of water to get a 65% solution. I assume it is 100 grms but I do not wish to make an error.
Would appreciate any advise.
Regards Global92

Since you are using calcium hypochorite, the formula is as follows:

Wgt of Calcium Hypo(gms) = liters of water * 1000 gms/liter*
solution strength / hypo %

So, Wht of Calcium Hypo(gms) = 1 liter * 1000gms/L * .03/.65
= 46.15 grams of Calcium Hypo
