How would you usually prepare starch indicator solution for iodine titrations? Can the solution be stored for a few months in the fridge?
I noticed that sometimes the starch indicator solution in the fridge has turned cloudy, in which case we should prepare a new solution?
I've never tried storing starch indicator in a refrigerator. I've ALWAYS made it fresh and use it the same day. I don't trust it more than a day although I've seen it stay ok for 2-3 days. Still, it's so easy to make I make it fresh each day.
