The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n When the ionic compound (NH\u2084)\u2082SO\u2083<\/strong> (ammonium sulfite) dissolves in water, it dissociates completely into its constituent ions:<\/p>\n\n\n\n [ Now, let’s analyze whether these ions react significantly with water.<\/p>\n\n\n\n The ammonium ion (NH\u2084\u207a)<\/strong> is the conjugate acid of ammonia (NH\u2083), which is a weak base. In water, NH\u2084\u207a undergoes hydrolysis to a considerable extent:<\/p>\n\n\n\n [ This reaction releases hydronium ions (H\u2083O\u207a), making the solution slightly acidic. Since this reaction is significant and contributes to the pH of the solution, the ammonium ion does react with water to a considerable extent<\/strong>.<\/p>\n\n\n\n The sulfite ion (SO\u2083\u00b2\u207b)<\/strong> is the conjugate base of sulfurous acid (H\u2082SO\u2083), which is a weak acid. It can undergo hydrolysis in water:<\/p>\n\n\n\n [ However, the extent of this reaction is less significant<\/strong> compared to NH\u2084\u207a because H\u2082SO\u2083 is a weak acid, and SO\u2083\u00b2\u207b is not highly reactive in water. Although it can slightly increase the pH, the effect is not as strong as NH\u2084\u207a’s effect in making the solution acidic.<\/p>\n\n\n\n Since NH\u2084\u207a hydrolyzes significantly<\/strong>, whereas SO\u2083\u00b2\u207b does so only weakly, the correct answer is cation (NH\u2084\u207a)<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":" When the ionic compound (NH4)2SO3 is dissolved in water, which species will react with water to a considerable extent?
