Is it magnesium?

  1. Mar 15, 2016 #1
    I have a bottle with some vitamin capsules that got mixed up with other vitamins and I can't remember what it is but I'm almost sure it's magnesium.

    Is there a test I can do like drop the powder of the capsule into some kind of liquid and I would be able to tell if it's magnesium?

    It would be a magnesium compound - which in theory could be discovered with a home spectrometer.
    But in all practicality - NO.

    If there is any significant risk of harm, I would strongly advise tossing all the pills out.

    The pills probably cost less than $20. Small insurance.

    I'm sorry but this is just asking for trouble. Please get new bottles of vitamins if you can't tell what's what. Thread locked.
