2025年1月31日 · Potassium chloride (KCl), ionic compound whose molecules consist of one potassium atom and one chlorine atom. It is a white-to-colourless face-centred cubic crystal. Potassium chloride can be extracted from sylvinite, a mineral mixture of sodium chloride (halite) and potassium chloride (sylvite),

Potassium chloride (KCl, or potassium salt) is a metal halide salt composed of potassium and chlorine. It is odorless and has a white or colorless vitreous crystal appearance. The solid dissolves readily in water, and its solutions have a salt-like taste. Potassium chloride can be obtained from ancient dried lake deposits. [7]

The concentration of the potassium iodide solution should be adjusted so that it gives a light brown solution on addition of chlorine water. If the reagents are too concentrated, a black precipitate of iodine often results instead of a brown solution.

Specifically, when dissolved in water, potassium chloride solutions are normally colorless. However, in the presence of certain anionic contaminants, KCl solutions can turn pink or red in color. This phenomenon has fascinated chemists and has practical implications for analytical chemistry techniques.

2024年6月3日 · A potassium chloride (KCl) solution is colorless.

Add 75 mL of hydrochloric acid and 5 mL of chloroform, and adjust to a faint iodine color (in the chloroform) by adding dilute potassium iodide or potassium iodate solution. If much iodine is liberated, use a stronger solution of potassium iodate than 0.01 M at first, making the final adjustment with the 0.01 M potassium iodate.

2018年9月25日 · 》The colour of potassium chloride(Kcl) is white. 》potassium brombide(Kbr)=>Pink in colour. 》Potassium iodide(ki)=>Yellowish brown in colour. Hope it helps..☆☆

Test solution— Dissolve 2 g of Potassium Chloride in 8 mL of water. Add 1 mL each of chloroform and diluted hydrochloric acid, then add 5 drops of a chloramine T solution (1 in 100), and shake gently. The brown color of the chloroform layer is not darker than that of a concomitantly prepared Standard solution: the limit is 0.1%.
