A/B Extraction Hcl PH ? | Bookmark | ||||||
when an a/b extraction is done at the end of the cyano/amm acetate/methanol method for mda - swim knows to take the ph of the naoh step to 11, but in the previous 10% hcl step, is there a ph one should shoot for to ensure the hcl gets (extracts) all the freebase out? Is there some other way to make sure one has got all the freebase out ? (other than a huge amount of 10%hcl) Also, does anyone know how swim would figure out what % store bought pool cleaner is that says (20-30% hcl) on the label? Would it be bad to have a much lower or higher than 10% hcl solution (if swim just assumed it was say 25% and it wasn't)? |

You could measure density to find out the %. | Bookmark | ||||||
You could measure density to find out the %.Give a specific gravity of your HCl and i'll post the % A friend with speed is a friend indeed |
