9C.3 7th edition

Postby Maggie Doan 1I » Mon Dec 03, 2018 4:57 pm

a)potassium hexacynidochromate (III) - the answer is K3 [Cr(CN)6]
How come the formulas don't have a charge when writing from the coordination compounds and why is it K3?

d)soduim bisoxaltodiaquaferrate(III) - Na[Fe(OH2)2(CO3)2]
Does the order of the ligands matter because I mixed up the (CO3)2 and the (OH2)2?

The formulas don't have a charge because the combination of K3 and [Cr(CN)6] combine with no net charge

I don't think order matters much when writing in the brackets, as long as your anions are correct. However, order does matter when naming!
