    Jun 10, 2017018332B. Changing of ironIII ions to ironII ions. Zinc powder reduces ironIII ions, Fe 3 to ironII ions, Fe 2. The presence of Fe 2 ions is confirmed by the formation of green precipitate with sodium hydroxide solution. Zinc atoms lose their electrons and are oxidised to zinc ions, Zn 2.This explains why zinc powder dissolves in ironIII sulphate solution.
