Zinc, magnesium and calcium in human seminal fluid: …
Introduction The total zinc content in semen from mammals is high, and zinc has been found to be critical to spermatogenesis. Deficiency of zinc is associated with hypogonadism and insufficient development of secondary characteristics in humans (Prasad, 1991), and can cause atrophy of the seminiferous tubules in the rat and hence failure in spermatogenesis (Millar et al., 1958; Underwood
Sodium silie - Wikipedia
Properties Sodium silies are colorless glassy or crystalline solids, or white powders. Except for the most silicon-rich ones, they are readily soluble in water, producing alkaline solutions.Sodium silies are stable in neutral and alkaline solutions.In acidic solutions, the silie ions react with hydrogen ions to form silicic acids, which tend to decompose into hydrated silicon dioxide gel.

One way to reduce sodium in our diet is to use Low Sodium Salt. This has two thirds of the sodium chloride replaced by potassium chloride. A national newspaper asked readers for their views on two options. Option 1: Ban the use of sodium chloride in foods.
Sodium | Article about sodium by The Free Dictionary
Sodium-potassium alloys containing 40–90 percent potassium (by weight) at about 25 C are silver-white liquids distinguished by their high chemical activity (they ignite upon exposure to air). The electrical conductivity and heat conductivity of liquid sodium-potassium alloys are both lower than the corresponding values for sodium and potassium.
