Web9 jan. 2024 · Cr3+ chromium(III) ion. Is Cr3+ diamagnetic or paramagnetic? Since there are 5 3d orbitals, they are not all at least singly filled yet, and thus, all three electrons in the lowest-energy configuration are unpaired. So, this is paramagnetic. WebThe differences in the slope of these curves arise from what is actually being measured. The normal range COD digestion is read at 420 nm and is proportional to the increase in the chromic ion (Cr3+), which causes the digestion solution to move towards a green shade as the concentration increases.
