[tex]= 4×(2.2×10-5)3[/tex]
[tex]= 4.25×10-14[/tex]
What is the solubility of Manganese(II) hydroxide ?
[tex]18 °C[/tex], the solubility in water is [tex]0.00034 g/100 mL[/tex].
id-soluble solubility
1.68 Refractive index (nD)
The inorganic chemical with the formula Mn(OH)2 is manganese(II) hydroxide. Although samples soon darken when exposed to air due to oxidation, it is a white solid. It doesn't dissolve well in water.
The solubility product constant can be calculated using the known molar solubility of manganese(II) hydroxide. The solubility product constant expression is presented below along with the balanced chemical equation for the sparingly soluble salt's dissolution:
[tex]Mn(OH)2 + 2 Na+ = Mn(2+) + 2 NaOH[/tex]
Darkening of samples indicates that manganese(II) hydroxide oxidizes easily in air.
Like several other metal hydroxides, the chemical adopts the brucite structure.
