I know that salt from the supermarket is not pure NaCl. It contains at least iodide if not other ingredients. So I can't use it for my self made Perceptol. The NaCl I bought was more expensive than just salt. So for me it's worth drying it.
By the way: I use the microvave only for photography/laboratory purposes.
...And if I look at my Iodide containing household salt, and do the calculation right, it contains about 150 microgram of Iodide per 6 grams of salt, that is less than 0.0025%!
Would that really matter :confused:
I guess my NaCl absorbed water because the bottom of the batch sticks to the paper after weighing. Is it possible to dry it in a microwave without damaging it? If yes, how long will it take to dry about 10 g?
