Comment: SSA from [VL00]; SSD at the dominant 110 face 3 sites/nm² [HVV96] for both site types; 001 and 021 faces at the top end of goethite needles have singly ccordinated surface groups (SSD = 7-8 sites/nm²); 90 % contribution of 110 face overall mean SSD; protonation constants se equal to the value of the PZC
