Melzer's reagent is an aqueous solution of chloral hydrate, potassium iodide, and iodine.Depending on the formulation, it consists of approximately 2.50-3.75% potassium iodide and 0.75–1.25% iodine, with the remainder of the solution being 50% water and 50% chloral hydrate.
Mayer's reagent is freshly prepared by dissolving a mixture of mercuric chloride (1.36 g) and of potassium iodide (5.00 g) in water (100.0 ml). [ 1 ] [ 2 ] Most alkaloids are precipitated from neutral or slightly acidic solution by Mayer's reagent ( potassiomercuric iodide solution) to give a cream coloured precipitate.
[2] The formation is as follows: The black precipitate of bismuth iodide is formed from the reaction of bismuth ion and potassium iodide. Bi 3+ + 3 KI → BiI 3 + 3 K + Then, the reaction between bismuth ion and excess potassium iodide will produce a soluble complex of potassium tetraiodobismuthate which has an orange color. BiI 3 + KI → K(BiI 4)
A solution of iodine I 2 is yellow/brown in color. When this is added to a solution to be tested, however, any chemical group (usually in this test −C=C− double bonds) that react with iodine effectively reduce the strength, or magnitude of the color (by taking I 2 out of solution). Thus the amount of iodine required to make a solution ...
Potassium iodide is a component in the electrolyte of dye sensitised solar cells (DSSC) along with iodine. Potassium iodide finds its most important applications in organic synthesis mainly in the preparation of aryl iodides in the Sandmeyer reaction, starting from aryl amines. Aryl iodides are in turn used to attach aryl groups to other ...
Plants vs. Zombies is a video game franchise developed by PopCap Games, a subsidiary of Electronic Arts (EA). The series follows the affiliates of David "Crazy Dave" Blazing as they use his plants to defend against a zombie invasion, led by Dr. Edgar George Zomboss.
Plants vs. Zombies 2 (originally subtitled: It's About Time) is a 2013 free tower defense video game developed by PopCap Games and published by Electronic Arts. It is the sequel to Plants vs. Zombies, and was released worldwide on Apple App Store on August 15, 2013, and Google Play on October 23, 2013. The player defends the lawn from zombies ...
For example, in the molecules represented by CH 3 X, where X is a halide, the carbon-X bonds have strengths, or bond dissociation energies, of 115, 83.7, 72.1, and 57.6 kcal/mol for X = fluoride, chloride, bromide, and iodide, respectively. [2] Of the halides, iodide usually is the best leaving group.
