Manganese(II) sulfide is one of the compounds found in the nodules on the ocean floor that may eventually be a primary source of many transition metals. The solubility of MnS is 4.7X10⁻⁴g/100. mL solution. Estimate the Ksp of MnS.

Respuesta :

The Ksp of MnS is  [tex]2.9[/tex]×[tex]10^{-9}[/tex].

Steps

equation

MnS--->[tex]Mn^{+2}[/tex](aq) + [tex]S^{2}[/tex](aq)

Ksp= [[tex]Mn^{+2}[/tex]][[tex]S^{2}[/tex]]

      =[tex]S^{2}[/tex]

S= 4.7 x [tex]10^{-4}[/tex]g/100ml

   =5.4 x [tex]10^{-5}[/tex]M

Ksp=(5.4 x [tex]10^{-5}[/tex]M)[tex])^{2}[/tex]

Ksp= [tex]2.9[/tex]×[tex]10^{-9}[/tex].

What is the purpose of manganese sulfide?

The characteristics and uses of nanosize MnS employed as optical, electric, and magnetic materials are grouped into three major categories. The high bandgap of MnS, among other appealing characteristics, makes it intriguing for emission in the UV area.

MnS—is it a salt?

Alabandite (isometric), rambergite (hexagonal), and recently discovered browneite are the minerals that represent it in nature (isometric, with sphalerite-type structure, extremely rare, known only from a meteorite).
