Roberto Hendrix · Answer 1

MgCl2 + KOH will yield a precipitate.

Explanation:

The pairs of aqueous solutions of which are listed above and the pair MgCl2 + KOH will yield a precipitate. Based on the solubility chart we can reason that Mg (OH) is examined as "insoluble", so it will form a precipitate where else the other reactions which are listed above are not stable and it quickly decomposes into water and carbon dioxide MgCl2 is used in the medical field for skin-related issues
