Intravenously, the LD 50 of potassium chloride is far smaller, at about 57.2 mg/kg to 66.7 mg/kg; this is found by dividing the lethal concentration of positive potassium ions (about 30 to 35 mg/kg) [34] by the proportion by mass of potassium ions in potassium chloride (about 0.52445 mg K + /mg KCl). [35]
In chemistry, the molar mass (M) (sometimes called molecular weight or formula weight, but see related quantities for usage) of a chemical compound is defined as the ratio between the mass and the amount of substance (measured in moles) of any sample of the compound. [1] The molar mass is a bulk, not molecular, property of a substance.
A chloride ion is a structural component of some proteins; for example, it is present in the amylase enzyme. For these roles, chloride is one of the essential dietary mineral (listed by its element name chlorine). Serum chloride levels are mainly regulated by the kidneys through a variety of transporters that are present along the nephron. [19]
Potassium chloride and potassium bicarbonate may be useful to control mild hypertension. [132] In 2020, potassium was the 33rd most commonly prescribed medication in the U.S., with more than 17 million prescriptions.
For example, potassium oxide is about 83% potassium by weight, while potassium chloride is only 52%. Potassium chloride provides less potassium than an equal amount of potassium oxide. Thus, if a fertilizer is 30% potassium chloride by weight, its standard potassium rating, based on potassium oxide, would be only 18.8%.
Molar mass: 122.55 g ... is the inorganic compound with the molecular formula ... by the salt metathesis reaction of sodium chlorate and potassium chloride:
Potassium chlorite is a potassium salt of chlorous acid (HClO 2) having a chemical formula KClO 2. It exists as white powder and its annhydrous form easily undergoes decomposition in presence of heat or radiation (especially gamma rays ).
potassium permanganate has a molar mass of 158.034(1) g mol −1, and reacts with five moles of electrons per mole of potassium permanganate, so its equivalent weight is 158.034(1) g mol −1 /5 eq mol −1 = 31.6068(3) g eq −1.
