RE: Dilution question

However, the dilution is so small, what are you doing about the decay of this compound? Jon, I am wonder where you are using this (PT/PD) printing presumably. Are you looking to keep the fog threshold up a touch?

Subject: Dilution question


Hi list,

Can anyone help me figure out the following dilution? I have a solution that is 10% potassium chlorate. I have in the past diluted this down to 5% and 1% and a 1/2% solutions. I rarely use any and cannot find my notes for making the dilutions.

I now want to make a tiny dilution, like 0.125%, or similar, just so there is a presence of potassium chlorate in the sensitiser. Could someone help me get there from the 10% start?
