WebA classical method of analysis for unknown samples containing iron is to add NaOH or NH3. This precipitates Fe(OH)3, which can then be filtered and weighed. To demonstrate that the concentration of iron remaining in solution in such a sample is very small, calculate the solubility of Fe(OH)3in moles per liter and in grams per liter. WebSuppose the molar solubility of nickel hydroxide. Ni (OH)2, is x M. Show that Ksp for nickel hydroxide equals 4x3. Calculate the solubility (in grams per liter) of magnesium hydroxide in the following. (a) pure water (b) 0.041 M Ba (OH)2 (c) 0.0050 M MgCl2.
