A student measures the S2- concentration in a saturated aqueous solution of iron(II) sulfide to be 2.29×10-9 M. Based on her data, the solubility product constant for iron(II) sulfide is

Ksp FeS = 5.2441 E-18

Explanation:

         S          S           S

∴ Ksp = [Fe2+]*[S2-]solubility product constant

∴ [S2-] = 2.29 E-9 M = S

⇒ Ksp = (S)(S) = S²

⇒ Ksp = (2.29 E-9)²

⇒ Ksp = 5.2441 E-18

passing a magnet thought the

mixture , because iron gets attracted to magnet .

the answer is the first option

explanation:

just googled it m8. not that hard

lol
