18. Solving a chemistry problem

6. Prepare a solution of Mohr´s salt ((NH4)2SO4*FeSO4) in a test tube by dissolving a micro spatula of salt in 4 drops of water, or take a freshly prepared solution of Mohr´s salt and add 2 M alkali solution to it until a light green precipitate of iron hydroxide (II ). Quickly divide the resulting precipitate into 2 parts, dissolve one part in a hydrochloric acid solution, and stir the other part with a glass rod and observe after 1 minute a color change due to the oxidation of the hydroxide. Write the equations for all the reactions that take place. What properties does Fe (OH) 2 exhibit in these reactions
