1. a. i. Ammonium hexaaquachromium (III) sulfate is the name. Along the way, I had thought of hexaaquachromo ammine sulfate and hexaaquaammine chromium (III) sulfate. ii. chromi b.potassium hexacyanoosmium (II) c. i. tetraamminediaquanickel (II) nitrate tetraamminediaquanickelate nitrate ii. +2 is Nickel's oxidation state d. i. hexacarbonylmolybdenum(0) is the name. hexacarbonylmolybdenate ii. the oxidation state of molybdenum is zero iii. molybdenum has five 5 d electrons 2. a. Following Petrucci Table 25.5 page 881 sveneth edition, as well as the photo on the next page upper left hand corner Compound A the green one is [CrCl2(H2O)4]Cl.
Compound B the violet one is [Cr(H2O)6]Cl3.
Compound C the blue-green one is [CrCl(H2O)5]Cl2.
b) COmpound A is called tetraaquadichlorochromium(III) chloride. I goit the name of the ion from http://www.chemguide.co.uk/inorganic/complexions/ligandexch.html COmpound B is called hexaaqua Chormium 3. CoNH33H2O 4. a. By tridentate what is meant is that it bites into three different places. d. It is diamagnetic rather than paramagnetic. http://www.chemguide.co.uk/inorganic/complexions/ligandexch.html
