About Iron Solute[]

Iron solute is used for many things. It can be used for metalworking and chemistry.

For a historical perspective, it is likely simply iron (II) ions within an aqueous medium. The book mentions that iron solute is used in printer ink. Since iron solute does not exist within chemistry, the next best thing is analyzing what is used to make said ink. In this case, it is usually made with iron (II) sulfate dissolved in a solution of tannic acid.

Trivia[]

  • In the book, Amy says it is an ingredient for ink.
  • "Solute" means "dissolved in water" so "Iron solute" can be written Fe(II) (aq) or Fe(III) (aq). Fe (aq) unfortunately does not exist since metals are insoluble in water.
  • Grace Cahill wrote RESOLUTION as an anagram to it.
