  2. Transition metal complexes of thiocyanate - Wikipedia

    en.wikipedia.org/wiki/Transition_metal_complexes...

    Thiocyanate complexes are not widely used commercially. Possibly the oldest application of thiocyanate complexes was the use of thiocyanate as a test for ferric ions in aqueous solution. [14] The reverse was also used: testing for the presence of thiocyanate by the addition of ferric salts. The 1:1 complex of thiocyanate and iron is deeply red.

    Jannik Bjerrum (son of Niels Bjerrum) developed the first general method for the determination of stability constants of metal-ammine complexes in 1941. [1] The reasons why this occurred at such a late date, nearly 50 years after Alfred Werner had proposed the correct structures for coordination complexes, have been summarised by Beck and Nagypál. [2]

    Mercury(II) thiocyanate (Hg(SCN) 2) is an inorganic chemical compound, the coordination complex of Hg 2+ and the thiocyanate anion. It is a white powder. It is a white powder. It will produce a large, winding "snake" when ignited, an effect known as the Pharaoh's serpent .

    However, the equilibrium constant for the loss of two protons applies equally well to the equilibrium [M(H 2 O) n] z+ - 2 H + ⇌ [MO(H 2 O) n-2] (z-2)+ + H 2 O. because the concentration of water is assumed to be constant. This applies in general: any equilibrium constant is equally valid for a product with an oxide ion as for the product with ...

    [7] [8] [9] Thus the complete absence of thiocyanate or reduced thiocyanate [10] in the human body, (e.g., cystic fibrosis) is damaging to the human host defense system. [11] [12] Thiocyanate is a potent competitive inhibitor of the thyroid sodium-iodide symporter. [13] Iodine is an essential component of thyroxine. Since thiocyanates will ...

    Le Chatelier–Braun principle analyzes the qualitative behaviour of a thermodynamic system when a particular one of its externally controlled state variables, say , changes by an amount , the 'driving change', causing a change , the 'response of prime interest', in its conjugate state variable , all other externally controlled state variables remaining constant.
