Alkalinity or Acidity

The aqueous solution of ammonium chloride is known to be a weakly acidic and strong electrolyte. Upon dissolution in water, it ionises into ammonium ions and chloride ions, which react to produce ammonium chloride and white smoke. It is characterised by having no odour and a salty, cool, and slightly bitter taste. It should be noted that although it has low hygroscopicity, it can absorb moisture and form lumps in humid and rainy weather. That is soluble in water, slightly soluble in ethanol, and liquid ammonia, but insoluble in acetone and ether. Its solubility in water at 0℃ is 29.4 g, but hydrochloric acid and sodium chloride can reduce its solubility. When ionised ammonium ions undergo hydrolysis in water, the solution becomes acidic, and the pH value of saturated ammonium chloride solution at room temperature is generally around 5.6. The pH value varies depending on the concentration of the solution, with a pH of 5.5 at 1%, 5.1 at 3%, and 5.0 at 10% at 25℃. The solution exhibits a weakly acidic nature and may undergo decomposition upon heating. It is important to note that its acidity tends to increase with temperature. Furthermore, when the solution is mixed with ammonia and hydrogen chloride gas, it results in the formation of white smoke, which is identified as ammonium chloride. Moreover, it has been observed that the solution can cause corrosion in certain metals, particularly copper, but not in pig iron. Furthermore, when the solution is mixed with ammonia and hydrogen chloride gas, it results in the formation of white smoke, which is identified as ammonium chloride.
