Solid sodium sulfide is slowly added to 150 mL of a 0.454 M manganese(II) nitrate solution until the concentration of sulfide ion is 0.0268 M. The mass of manganese(II) ion remaining in solution is grams.
A sample of solid Mg(OH)2 was stirred in water at a certain temperature until the solution contained as much dissolved Mg(OH)2 as it could hold. A 450-mL sample of this solution was withdrawn and titrated with 0.00357 M HClO4. It required 58.3 mL of the acid solution for neutralization.What is the solubility of Mg(OH)2 in water, at the experimental temperature, in grams of Mg(OH)2 per liter of solution?
