does anyone know the substance that should be used for the experiment where you have1ml of 1% concentrated substance(im going to call it substance X) in a test tube, you add 9ml distilled water, mix and subract 1ml from the test tube with a pipette.you empty the pipette into test tube 2 and add 2 drops of iodine to test tube 1. you repeat this for about 5 test tubes and then test how strong the colour is. it was a practical i did in biology but i can't remember the name of it.
i'm supposed to write a method for it but can't remember what substance we were using.
if anyone managed to make sense of what i just said, could you please help me out?

1.) Evaluate the field F=(x+yz)i+ (y+xz)j+(z+xy)k alond the straight line from (1,0,0) to (1,1,0) and then from (1,1,0) to (1,1,1).

2,) Evaluate the surface integral...
v=(y^2)i + (2xy+z^2)j+(2yz)k S; the unit cube centered at the origin.

3.) Evaluate the surface integral...
v=(2xz+3y^2) j + (4yz^2) k , S: the square in the yz-plane having corners (0,0,0), (0,1,0), (0,1,1), and (0,0,1).
