20 Oct 2023: ii) Calculate the saturation magnetisation of magnetite whose cubic cell has latticeparameter a = 8.39 Å.

The saturation indices computed by PHREEQC were positive for iron assemblages (i.e., iron hydroxides, goethite, hematite, jarosite, maghemite, and magnetite), while negative for arsenic assemblages (i.e., arsenolite, native arsenic,
