    • Precaution should be addressed while handling ammonia or aqueous ammonia. Ammonia is a toxic gas although its aqueous solution had been employed as a fertilizer in farms many years ago. The toxicity of ammonia solutions does not usually cause problems for humans and other mammals. However, ammonia even at dilute concentrations is highly toxic to aquatic animals. More details on the toxicity of ammonia could be obtained from the Internet: http://en.wikipedia.org. In our laboratory, the anion metathesis process was carried out in a fume hood, and the waste water containing ammonia was neutralized by diluted acetic acid before final disposal.
