FeOH2 is ferrous hydroxide or iron hydroxide. A sulfuric acid neutralizes excess hydronium ions in the sparse soluble iron salt mixture. Atmospheric oxygen is doing the oxidation I think of FeOH 2 to FeOH 3 which is even less soluble- this is why its purifying the MnOH 2 - which somehow dissolves and is left in solution with the chloride ions.

Answer 1 of 2. Sodium hydroxide also produces FeOH2and FeOH3from the corresponding oxidation states of iron in aqueous solution. Neither hydroxide precipitate dissolves in excess sodium hydroxide.

Now lattice energy is inversely proportional to the size of cations and size of anions. Ferrous hydroxide will be forced out of the solution as a precipitate because it isnt soluble in water. HNO3 is a strong base and KNO3 is the salt of a strong base KOH and a.
