Iron (II) hydroxide, Fe(OH)2, is very insoluble in water. Hence, if it is produced during an aqueous reaction it will precipitate from solution. How many grams of sodium hydroxide (a strong base) must be added to 27.7 mL of a 0.305 M aqueous solution of iron (II) nitrate, in order to precipitate all of the iron as Fe(OH)2? Assume that the solid that you add does not change the volume of the solution.
