Pay Now | Na4Fe(CN)6· 10 H2O. 17.1K views. 36 is stable configuration. 4 moles K4Fe(CN)6 to grams = 1473.3704 grams. Therefore van't hoff factor = 5 . subject. Structure. askiitians. WKT the sum of charges of the compound is zero. 5 moles K4Fe(CN)6 to grams = 1841.713 grams. Similarly for BaCl 2, Von’t Hoff factor is 3 n factor is the number of electron transfer for single atom or the oxidation state of the central atom Look CN is a strong field ligand hence it will pair up the electrons hence forming low spin complex as by VBT. We definitely have six triple C-N bonds and six single C-Fe bonds in the [Fe(CN)6](4-) complex. askiitians. grade, Please choose the valid Which is the best book for neet biology? Therefore, iron has an oxidation number of +2. The oxidation number of Fe in K4Fe(CN)6 can be calculated as follows, 4(+1) + x + 6(-1) = 0 Hence x = +2. n factor is the number of electron transfer for single atom or the oxidation state of the central atom , 7. He recorded the anodic peak intensity (i p) corresponding to the oxidation of Fe(II) to Fe(III) as a function of the scanning speed (v) of the CV (see table). I smell smoke in my house but can't figure … For a very dilute aqueous solution of K4Fe(CN)6, van't Hoff factor (A) i = 11 (B) i = 5 (C) i = 1/11 (D) i = 10. ionic bonds as well, for a total of 16(?). subject.
