Is Ni CN 4 paramagnetic?
NiCl42− and [Ni(CN)4]2− are diamagnetic and Ni(CO)4 is paramagnetic.
What does cotton dissolve in?
Cotton is a robust fibre and alkalies have no to little effect on cotton, but yes, cotton is soluble in Sulphuric acid with 70% solution at room temperature.
What can tetraamminecopper ( II ) sulfate be used for?
Tetraamminecopper (II) sulfate. This dark blue solid is a metal complex with faint odor of ammonia. It is closely related to Schweizer’s reagent, which is used for the production of cellulose fibers in the production of rayon. It is used to print fabrics, used as a pesticide and to make other copper compounds like copper nano-powder.
Where does the blue colour of tetraammine come from?
The combination of the correct concentrations will produce the highest absorbance read out on the colorimeter and as a result the formula of the complex can be verified. The characteristic deep blue colour of the tetraammine complex is found in brass and copper alloys where attack from ammonia has occurred, leading to cracking.
How is copper sulfate pentahydrate prepared as a compound?
This compound can be prepared by adding concentrated solution of ammonia to a saturated aqueous solution of copper sulfate pentahydrate followed by precipitation of the product with ethanol or isopropanol. The deep blue crystalline solid tends to hydrolyse and evolve (release) ammonia upon standing in air.
How is the bond length of copper sulfate measured?
The bond length between the atoms in the crystal are measured using X-ray crystallography; the Cu-N and Cu-O distances are about 210 and 233 pm, respectively. The correct concentrations of ammonia and copper sulfate solution needed to synthesize the complex can be determined by colorimetry.
