Hello
Can somebody please provide me with some assistance to this question? I have attached an image to verify what I mean, but for our Iodine Clock practical we have to design a procedure similar to Part A for Part B but Iodide ions are now the variable and Peroxydisulfate is the constant. What would the steps be? I assume it is very similar to Part A, but steps 2 and 3 are throwing me off...would Step 2 be add 10mL of Peroxydisulfate and Step 3 be to add 10mL of Thiosulfate (S2O3^2) before adding Iodide ions in step 5 as that is the concentration variable?? I don't understand why adding Peroxydisulfate and Thiosulfate ions would even do anything before adding the Iodide ions anyway?
If somebody please could verify the Part B procedure that would be fantastic as I'm struggling for such an easy task!
Thanks
