Hi: I'm not the greatest when it comes to titration mathematics.
Can someone here show me the formula for dilution. I knew how to do this once but I just can't remember now. Problem: wish to put an unknown volume of 35% H2O2 into a 250 ml and a 500 ml container and fill with distilled water to obtain 3%. Equipment: 35% H2O2, 250 and 500 ml containers and a 30 ml measuring cup divided off in 5 ml lines, drams at the 1/4 oz markers, 1/4 oz markers - and of course distilled water. Thanking you in advance. IanRoe
