Is merthiolate and mecurichrome that same thing? I don't remember what mom used but it STUNG!!
Other than both compounds containing mercury they are different. Though both are orange and stung like mad, apparently! Today, most people would know merthiolate is thiomersal (molecular formula: C9H9HgNaO2S). Mercurachrome is a trade name for merbromin (molecular formula: C20H8Br2HgNa2O6).
