They are essentially <strong>spectator ions<\/strong> in acid-base chemistry and do not act as bases in water.<\/p>\n\n\n\n<p><strong>H\u2082O<\/strong>, while a neutral molecule, can act as a very weak base, but it is far weaker than the others on this list.<\/p>\n\n\n\n<p><strong>OH\u207b (hydroxide)<\/strong> is a strong base because it is the conjugate base of water, a very weak acid. <strong>HS\u207b<\/strong> is a moderately strong base because H\u2082S is a weak acid.<\/p>\n\n\n\n<p>However, <strong>NH\u2082\u207b (amide ion)<\/strong> is the <strong>strongest base<\/strong> on this list. It is the conjugate base of ammonia (NH\u2083), which is a weak acid. The nitrogen atom in NH\u2082\u207b is less electronegative than oxygen, meaning it holds onto the negative charge less tightly, making the lone pair on nitrogen <strong>more available to accept a proton<\/strong>. This makes NH\u2082\u207b highly reactive and basic in aqueous solutions.<\/p>\n\n\n\n<p>In summary, the strength of a base is inversely related to the strength of its conjugate acid. Since ammonia (NH\u2083) is a much weaker acid than water or H\u2082S, its conjugate base (NH\u2082\u207b) is stronger than OH\u207b or HS\u207b.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>Therefore, the strongest base is NH\u2082\u207b.<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-368.jpeg\" alt=\"\" class=\"wp-image-233933\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Which of the following is the strongest base?
