1.The following is a list of methods for the preparation of salts: A – direct combination of two elements. B – reaction of a dilute acid with a metal. C – reaction of a dilute acid with an insoluble base. D – titration of a dilute acid with a solution of soluble base. E – reaction of two solutions of salts to form a precipitate. Which method from the list A to E is the best for preparing **anhydrous ferric chloride**, and what is the suitable equation for this preparation?
- A.Direct combination: 2Fe + 3Cl₂ → 2FeCl₃
