tried a soap titration on dry washed bd but instead of 100ml of iso and 10g bd i went with 10ml iso 1gram bd scales weigh to.00, some bromo went dark blue instantly then added .01N hcl needed .029ml multiply that by 302.5 koh i get 92.9624 am not sure if this is 92ppm or 929 or 9296 have i stuffed it cheers andy

gilfish,
To determine soap ppm, the formula is:
Soap ppm (KOH) = ml HCl x Normality x 320,400/g sample

gilfish,
I made a mistake in the previous post. The 304,400 should be changed to 320,400 for KOH.
This is the formula I have been using as I read it on here from CGC.
I've never tried to discect the math though until today and I'm not so certain it's correct, or my brain isn't functioning properly. I'm going to start another discussion maybe someone can help out.

gilfish,
The formula from GCG is spot on.
My math/ train of thought was incorrect. My appologies.
