  1. Impressing! Does Na2S2O5 reduce Cl +5 to Cl (0) evolving Cl2 gas?

    Can you give me the chemical equation for this? Thanks!

  2. “eh doesn’t look like it’s doing anything…

    ohhh cool some bubbles!! nice (about to click away) wow it turns yellow too? ohhhHHO shit now it exploded”

  3. Dumb question, but how come it takes a short while before the reaction takes place, why is it not instantaneous? As the solution is not agitated after the substance is added why would there be a delay?
