Want composition of ferroxyl indicator for corrosion experiment
Q. Hi,
I hope you are able to solve my question: I would to find out the AMOUNT OF CHEMICAL CONTENTS in Ferroxyl Indicator (a saline solution containing potassium_ferricyanide
[affil links] and phenolphthalein
⇦ this on
eBay &
Amazon [affil links]
).
I am going to do an experiment on corrosion of materials. One of the requirements is to carry out an experiment to watch the changes by adding to the sodium chloride solution a few drops of ferroxyl indicator.
After that I will observe the anodic area turn blue showing the ferrous ion (i.e. corrosion) and so on and so forth.
Thank you & regards,

Q. Hi I'm a secondary school student and I've got a question to ask:
I would like to know what indicator (apart from potassium hexacyanoferrate) could I use in the experiment of the corrosion of metal to detect Fe3?
Thank you.
