Ian:

Don't make a mistake, instead use the form:

On the page, you can see the annotated algebra I used for designing the 
titration calculations.

Not that I'm a big fan of lazy math, but misplacing a decimal point is not a 
good idea with H2O2.

Let me know if you have any questions,

Kind Regards

Jason

  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.
