Calomel is a mercury chloride mineral with formula Hg 2 Cl 2 (see mercury(I) chloride). It was used as a medicine from the 16th to early 20th century, despite frequently causing mercury poisoning in patients. [5] The name derives from Greek kalos (beautiful) and melas (black) because it turns black on reaction with ammonia. This was known to ...
Mercury(I) chloride is the chemical compound with the formula Hg 2 Cl 2. Also known as the mineral calomel [4] (a rare mineral) or mercurous chloride, this dense white or yellowish-white, odorless solid is the principal example of a mercury(I) compound. It is a component of reference electrodes in electrochemistry. [5] [6]
The aqueous phase in contact with the mercury and the mercury(I) chloride (Hg 2 Cl 2, "calomel") is a saturated solution of potassium chloride in water. The electrode is normally linked via a porous frit (sometimes coupled to a salt bridge ) to the solution in which the other electrode is immersed.
The silver chloride electrode is most commonly used as a reference electrode in pH meters, although some designs use the saturated calomel electrode. The silver chloride electrode is simple to manufacture and provides high reproducibility. The reference electrode usually consists of a platinum wire that has contact with a silver/silver chloride ...
It was also used for scaling in psoriasis, to treat pruritus ani, and against pinworm and ringworm infection (especially in dogs), against crab louse infestation, [7] against lesions on the body and near eyes, against bumblefoot infection on poultry, and as a disinfectant. [11] [13] Chronic use of this medication can lead to systemic mercury ...
Mercury poisoning is a type of metal poisoning due to exposure to mercury. [3] Symptoms depend upon the type, dose, method, and duration of exposure. [3] [4] They may include muscle weakness, poor coordination, numbness in the hands and feet, skin rashes, anxiety, memory problems, trouble speaking, trouble hearing, or trouble seeing. [1]

Due to the strategic importance of supply-chain management, forward-looking control requirements must be taken into account. Because of the complexity of a supply chain, a focus on interface management is necessary. In the literature, several tasks and functions are defined. Management accounting in supply chains has the following features ...
