  2. Potassium chloride - Wikipedia

    en.wikipedia.org/wiki/Potassium_chloride

    Potassium chloride is inexpensively available and is rarely prepared intentionally in the laboratory. It can be generated by treating potassium hydroxide (or other potassium bases) with hydrochloric acid: + + This conversion is an acid-base neutralization reaction. The resulting salt can then be purified by recrystallization.

  4. Potassium chlorate - Wikipedia

    en.wikipedia.org/wiki/Potassium_chlorate

    Potassium chlorate can react with sulfuric acid to form a highly reactive solution of chloric acid and potassium sulfate: 2 KClO 3 + H 2 SO 4 → 2 HClO 3 + K 2 SO 4. The solution so produced is sufficiently reactive that it spontaneously ignites if combustible material (sugar, paper, etc.) is present. Candy being dropped into molten salt

  5. Potassium hypochlorite - Wikipedia

    en.wikipedia.org/wiki/Potassium_hypochlorite

    It is the potassium salt of hypochlorous acid. It consists of potassium cations (K +) and hypochlorite anions (− OCl). It is used in variable concentrations, often diluted in water solution. Its aqueous solutions are colorless liquids (light yellow when impure) that have a strong chlorine smell. [1] It is used as a biocide and disinfectant. [1]

    The amine coats the KCl but not NaCl. Air bubbles cling to the amine + KCl and float it to the surface while the NaCl and clay sink to the bottom. The surface is skimmed for the amine + KCl, which is then dried and packaged for use as a K rich fertilizer—KCl dissolves readily in water and is available quickly for plant nutrition. [26]

    en.wikipedia.org/wiki/Universal_indicator

    Solution: The main components of a universal indicator, in the form of a solution, are thymol blue, methyl red, bromothymol blue, and phenolphthalein. This mixture is important because each component loses or gains protons depending upon the acidity or alkalinity of the solution being tested. It is beneficial to use this type of universal ...

    2 kcl + 2 h 2 o → 2 koh + cl 2 + h 2 Hydrogen gas forms as a byproduct on the cathode ; concurrently, an anodic oxidation of the chloride ion takes place, forming chlorine gas as a byproduct. Separation of the anodic and cathodic spaces in the electrolysis cell is essential for this process.
