The tin chloride aids in the decomposition of the ore by reducing the iron(III) oxides to iron(II). More tin chloride should be added during the dissolution process to aid in dissolving the sample and to eliminate the yellow color which is characteristic of iron(III) chloride complexes. Avoid an excess of tin(II) chloride, however.
