Question

suggest a balanced equation for production of insoluble salt by direct combination​

Answer 1

Answer:

Sometimes it isn't appropriate to prepare a soluble salt by reacting an acid with an insoluble base or alkali, so it may be possible to prepare the salt by directly combining the metal and the non-metal elements.

Two such examples are the preparation of anhydrous aluminium chloride and anhydrous iron(III) chloride (anhydrous here means without any water of crystallisation).
