If you're not too picky (IOW, you want something close to 3% and aren't using it for quantitative analysis), and since H2O2 and water have about the same weight per volume -- just mix 1 part H2O2 with 11 parts of water. That'll produce about 3% H2O2. (A 1/9 mixture will be 3.5%). -- Dean -- from (almost) Des Moines -- KB0ZDF -- The silver-list is a moderated forum for discussion of colloidal silver.
