Preparation Of Hexaamminenickel Ii Chloride
Hexaamminenickel chloride is the chemical compound with the formula ni nh 3 6 cl 2 it is the chloride salt of the metal ammine complex ni nh 3 6 2 the cation features six ammonia called ammines in coordination chemistry ligands attached to the nickel ii ion.
Preparation of hexaamminenickel ii chloride. In my last post i showed the synthesis of hexamminenickel ii chloride. Hexamminenickel ii chloride analysis 3 9 calculate the millimoles of nh3 reacted with hcl according to reaction 3. Mostly putting it here as i found it interesting and because really chemistry is bloody awesome. In this experiment we will synthesize the complex salt hexamminenickel ii chloride.
Properties and structure ni nh 3 6 2 like all octahedral nickel ii complexes is paramagnetic with two unpaired electrons. Hexaamminenickel ii h18n6ni 2 cid 6857628 structure chemical names physical and chemical properties classification patents literature biological. 255807 hexaamminenickel ii chloride email this page to a friend.

Hexaamminenickel ii chloride is generally immediately available in most volumes. I don t know about the nickel complex but the copper easily gives up its ammonia for water so you have to be quick. Iodide compounds are used in internal medicine. Treating an iodide with nickel dioxide and sulfuric acid sublimes the iodine.
This is a brief version of a lab writeup i recently performed. I found the best way to get a good yield was to filter and dry it asap. Oooh i like this. The reagent forms a red square planar complex with ni2 in slightly alkaline solution.
In this follow up i wish to show how we determined the percentage of nickel in the resultant product via gravimentric analysis using butandionedioxime dimethyl gyoxime. Linear formula ni nh 3 6 cl 2. But i love the color. 12 calculate the mean and standard deviation of the three results in step 11.
11 calculate the percent by mass of nh3 in the three samples. Ive made this with copper sulfate before forming tetraaminecopper ii sulfate. 10 calculate the mass of nh3 molecular weight 17 03 g mol in the complex salt in each flask. 255807 sigma aldrich hexaamminenickel ii chloride 99 999 cas number 10534 88 0.
In the next experiment we will analyze for the percent ammonia in this salt. In this video the preparation of a complex is shown which is often made by students at universities. High purity submicron and nanopowder forms may be considered. In the laboratory 1 use an analytical balance to tare a weighing dish and then weigh out anywhere from 4 0 to 4 5 g of nickel chloride.
2 is called hexamminenickel ii ion.
