    Best method for the analysis of vitamins and metals in health supplements?

    I am looking at analysing a range of vitamin supplements in order to quantify both their water soluble vitamin and metal content. I intend to use LC-MS for the vitamins and FAAS for the metals. Are these the best methods would you say or is there a better method? Also I am not 100% sure on the...

    Balancing equation by Half-Reaction method

    How do I balance the following equation by the half-reaction method? The reaction takes place in basic solution. Fe(OH)2(s) + O2(g) = Fe(OH)3(s) The answer is 4Fe(OH)2(s) + 2H2O(l) + O2(g) = 4Fe(OH)3(s). How do I work it out? Please show steps.
