FeSO4 2 NaOH → Fe(OH)2 Na2SO4 • The interaction between Fe (II) ions and sodium hydroxide. • Double Displacement reactions are a common occurrence on my Instagram page. Mostly because they are easy to demonstrate, they are usually very visual, as they can demonstrate clearly to the viewer a chemical reaction has occurred. A straight forward way of describing any particular reaction is AB CD = AD CB. Today we have such a reaction, a gelatine’ish’ precipitate of iron hydroxide along with sodium su
