- How do we know the coordination number was 6? How do I find out the actual representation of the complex?give examples of the following: 1. Drugs in the market which are either salt crystals or co-crystal. 2. Drugs which are formed through complexation.(a) In early studies it was observed that when the complex [Co(NH3)4Br2]Br was placed in water, the electrical conductivityof a 0.05 M solution changed from an initial value of191 ohm-1 to a final value of 374 ohm-1 over a period of anhour or so. Suggest an explanation for the observed results.(b) Write a balanced chemical equation to describe the reaction.(c) A 500-mL solution is made up by dissolving 3.87 g ofthe complex. As soon as the solution is formed, and beforeany change in conductivity has occurred, a 25.00-mLportion of the solution is titrated with 0.0100 M AgNO3solution. What volume of AgNO3 solution do you expectto be required to precipitate the free Br-(aq)? (d) Based onthe response you gave to part (b), what volume of AgNO3 solution would be required to titrate a fresh 25.00-mL sampleof [Co(NH3)4Br2]Br after all conductivity changes haveoccurred?
- What structural distortions would you expect to occur in the complex LnM( eta 4- butadiene) if the ligands L were made more electron releasing?I'm struggling to understand magnetic moments. If [Mn(NCS)6]4- shiwed a value if 6.06 micro B, I guess that the complex would be low-spin. How would I show this and relate it to an energy level diagram showing the splitting of 3d orbitals? thankyou for any help .True or false: Coordination complexes are called such because they consist of ions or molecules that are bound to ha halogenated metal
- Can someone help me with a question. Determine the critical cation to anion ratio (Rx/Rz) that separates cubic coordination (8-fold) from octahedral coordination (6-fold). Use the figures below to guide you through your calculation.Draw a reasonable structure for a complex between Fe3+ and nitrilotriacetic acid, N(CH2CO2H)3.A 3.03-g petroleum specimen was decomposed by wet ashing and subsequently diluted to 500 mL in a volumetric flask. Cobalt was determined by treating 25.00-mL aliquots of this diluted solution as follows: Assume that the Co(II)-ligand chelate obeys Beer’s law, and calculate the percentage of cobalt in the original sample.
