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]
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 ...
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.
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]
ISO 22000 is the most popular voluntary food safety international standard in the food industry with 51,535 total number of sites (as per the ISO Survey 2022).The ISO 22000 family are international voluntary consensus standards which align to Good Standardization Practices (GSP) [3] and the World Trade Organization (WTO) Principles for the Development of International Standards.

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 ...
[14]: 2 Supply chain management was then further defined as the integration of supply chain activities through improved supply chain relationships to achieve a competitive advantage. [12] In the late 1990s, "supply chain management" (SCM) rose to prominence, and operations managers began to use it in their titles with increasing regularity.
