How to change conc. of H2O2..?
I am preparing for my A2 practical and am carrying out a rates of reaction experiment using hydrogen peroxide and sodium thiosulfate. I need to use a 2 volume solution of hydrogen peroxide, but i have a 100 volume solution. How do I make a 2 volume solution from the 100 volume solution? Or a 100 volume solution to a 20 volume solution?
Thank you.
Thank you.
