Lead(II) azide is prepared by the reaction of sodium azide and lead(II) nitrate in aqueous solution. [6] [5] Lead(II) acetate can also be used. [7] [8] Thickeners such as dextrin or polyvinyl alcohol are often added to the solution to stabilize the precipitated product. In fact, it is normally shipped in a dextrinated solution that lowers its ...
In a liquid state, sodium is completely miscible with lead. There are several methods to make sodium-lead alloys. One is to melt them together and another is to deposit sodium electrolytically on molten lead cathodes. NaPb 3, NaPb, Na 9 Pb 4, Na 5 Pb 2, and Na 15 Pb 4 are some of the known sodium-lead alloys.
Lead (/ l ɛ d /) is a chemical element; it has symbol Pb (from Latin plumbum) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to ...
The temperature is cooler at the bottom and hotter at the top so that the sodium hydroxide is solid in the neck (B) and liquid in the body of the vessel. Sodium metal forms at the cathode but is less dense than the fused sodium hydroxide electrolyte. Wire gauze (G) confines the sodium metal to accumulating at the top of the collection device (P ...
A Consumer Reports' study found that grab-and-go meals like Lunchables can contain high levels of lead and sodium. High amounts of lead and sodium found in Lunchables, new report finds. Here's ...

Sodium: Primarily responsible for regulating fluid balance and maintaining blood pressure, sodium also supports nerve and muscle function. It's found in many foods and is often added to foods as salt.
Consumer Reports tracked the amount of lead in Lunchables by percentage of California’s maximum allowable dose level, which is 0.5 micrograms per day for lead.
