CaCl₂ + 2NH₃ + 2H₂O ↔ Ca(OH)₂ + 2NH₄Cl

Also, in the same way that water forms a hydrate, NH3 forms an ammine. (Does the book say "additional" or "addition"?)

[johnson039 (OP)]

does that mean formation of calcium complex ion? with NH3 as ligand?

[Bored chemist]

Yes.

If useful to someone, this man had no problem at all mixing calcium chloride and ammonia...
