This occurs when the salt is formed from a strong base and a weak acid. The character of a salt is determined by the properties of its constituent ions, specifically their ability to react with water in a process called hydrolysis.<\/p>\n\n\n\n<p>Let&#8217;s analyze each option:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>NH\u2084Br (Ammonium Bromide):<\/strong>\u00a0This salt is formed from a weak base, ammonia (NH\u2083), and a strong acid, hydrobromic acid (HBr). When dissolved in water, the ammonium ion (NH\u2084\u207a) acts as an acid by donating a proton to water, producing hydronium ions (H\u2083O\u207a) and making the solution acidic. The bromide ion (Br\u207b) is the conjugate base of a strong acid, so it does not react with water. The overall result is an acidic solution.<\/li>\n\n\n\n<li><strong>NaBr (Sodium Bromide):<\/strong>\u00a0This salt is formed from a strong base, sodium hydroxide (NaOH), and a strong acid, hydrobromic acid (HBr). Neither the sodium ion (Na\u207a) nor the bromide ion (Br\u207b) undergoes significant hydrolysis. They are spectator ions. Therefore, a solution of NaBr is neutral, with a pH of approximately 7.<\/li>\n\n\n\n<li><strong>RbCl (Rubidium Chloride):<\/strong>\u00a0This salt is formed from a strong base, rubidium hydroxide (RbOH), and a strong acid, hydrochloric acid (HCl). Similar to NaBr, neither the rubidium ion (Rb\u207a) nor the chloride ion (Cl\u207b) hydrolyzes in water. This results in a neutral solution.<\/li>\n\n\n\n<li><strong>NaCN (Sodium Cyanide):<\/strong>\u00a0This salt is formed from a strong base, sodium hydroxide (NaOH), and a weak acid, hydrocyanic acid (HCN). In solution, the sodium ion (Na\u207a) is a neutral spectator ion. However, the cyanide ion (CN\u207b) is the conjugate base of a weak acid. It reacts with water by accepting a proton, which produces hydroxide ions (OH\u207b). This reaction, CN\u207b + H\u2082O \u21cc HCN + OH\u207b, increases the concentration of OH\u207b in the solution, making it basic.<\/li>\n<\/ol>\n\n\n\n<p>Therefore, among the choices provided, NaCN is the only salt that will form a basic solution upon dissolving in water<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner5-268.jpeg\" alt=\"\" class=\"wp-image-47691\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner5-268.jpeg 1024w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner5-268-300x300.jpeg 300w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner5-268-150x150.jpeg 150w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner5-268-768x768.jpeg 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Select the basic salt. ?
