Salts containing ammonium have what solubility in water?

Salts containing ammonium have what solubility in water?

• A. They are soluble
• B. They are insoluble
• C. They decompose in water
• D. They react with water to form gas

Answer: (A)

Salts containing ammonium dissolve in water because the ammonium ion (NH4+) forms favorable interactions with water molecules, pulling the solid apart into NH4+ and the accompanying anion. Water’s polarity stabilizes these ions, so the lattice energy of the solid is overcome and the salt disperses as hydrated ions. This is why ammonium salts are soluble in water. They don’t decompose or release gas under normal conditions, just dissociate into ions.
