When this salt dissolves in water, it dissociates into <strong>NH\u2084\u207a (ammonium ion)<\/strong> and <strong>NO\u2083\u207b (nitrate ion)<\/strong>.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>NH\u2084\u207a (ammonium ion)<\/strong> is the <strong>conjugate acid<\/strong> of ammonia (a weak base). It can donate a proton (H\u207a) in water, making the solution <strong>slightly acidic<\/strong>.<\/li>\n\n\n\n<li><strong>NO\u2083\u207b (nitrate ion)<\/strong> is the <strong>conjugate base<\/strong> of nitric acid, a strong acid. Since strong acids dissociate completely, their conjugate bases are very weak and <strong>do not affect the pH<\/strong>.<\/li>\n<\/ul>\n\n\n\n<p>Thus, the ammonium ion can <strong>undergo hydrolysis<\/strong> in water: NH4++H2O\u2192NH3+H3O+\\text{NH}_4^+ + \\text{H}_2\\text{O} \\rightarrow \\text{NH}_3 + \\text{H}_3\\text{O}^+NH4+\u200b+H2\u200bO\u2192NH3\u200b+H3\u200bO+<\/p>\n\n\n\n<p>This reaction <strong>increases the concentration of H\u2083O\u207a ions<\/strong>, making the solution <strong>acidic<\/strong>.<\/p>\n\n\n\n<p>Because only the ammonium ion reacts with water and not the nitrate ion, the net effect is an <strong>acidic solution<\/strong>, so the <strong>pH is below 7<\/strong>.<\/p>\n\n\n\n<p>This behavior is typical of salts formed from a <strong>strong acid and a weak base<\/strong>. The weak base does not neutralize the acid completely in terms of pH effect, so the resulting solution is acidic.<\/p>\n\n\n\n<p>Therefore, the best choice that matches both the chemical understanding and the answer format is:<\/p>\n\n\n\n<p><strong>&#8220;below 7; ammonium is a weak acid&#8221;<\/strong>.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"852\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-734.jpeg\" alt=\"\" class=\"wp-image-36031\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-734.jpeg 852w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-734-250x300.jpeg 250w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-734-768x923.jpeg 768w\" sizes=\"auto, (max-width: 852px) 100vw, 852px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>The pH of an aqueous ammonium nitrate (NH4NO3) solution is because .
