Webb16 apr. 2024 · Mg(OH) 2 is soluble in NH 4 Cl but insoluble in NaCI because the Mg 2+ is less reactive than Na + ion. Ammonium chloride, being a soluble salt, dissociates completely to form ammonium cation and chloride ions. The NH + 4 ions can act as an acid and neutralize the OH – ions to form ammonia and water.. ∴ The NH + 4 cations will … Webb13 juli 2024 · Both C a ( O H) X 2 and M g O H) X 2 are sparingly soluble in water, but completely ionize whatever amount dissolved in water giving O H X − ions. Thus, they are considered strong bases. – Mathew Mahindaratne Jul 13, 2024 at 12:35 @MathewMahindaratne I think this then becomes a very technical matter.
