Basicity in an aqueous solution generally arises from the hydrolysis of the anion of a salt, which can accept protons from water, thus increasing the concentration of hydroxide ions (OH\u207b) in the solution.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>AlCl\u2083 (aluminum chloride)<\/strong>: When dissolved in water, it dissociates into Al\u00b3\u207a and Cl\u207b ions. The aluminum ion (Al\u00b3\u207a) is a weak acid because it can hydrolyze in water to form Al(OH)\u2083 and release H\u207a ions, resulting in an acidic solution. Thus, it does not contribute to basicity.<\/li>\n\n\n\n<li><strong>NaBr (sodium bromide)<\/strong>: This salt dissociates into Na\u207a and Br\u207b ions. The Na\u207a ion is neutral and does not affect pH, while Br\u207b is the conjugate base of a strong acid (HBr) and does not hydrolyze in water. Therefore, NaBr solutions are neutral and do not form a basic solution.<\/li>\n\n\n\n<li><strong>CH\u2083COONa (sodium acetate)<\/strong>: Sodium acetate dissociates into Na\u207a and CH\u2083COO\u207b ions. The acetate ion (CH\u2083COO\u207b) is a conjugate base of acetic acid (a weak acid). In water, acetate can react with water in a hydrolysis reaction, producing CH\u2083COOH and OH\u207b ions:<br>[<br>CH\u2083COO\u207b + H\u2082O \\rightleftharpoons CH\u2083COOH + OH\u207b<br>]<br>This reaction results in an increase in OH\u207b concentration, making the solution basic.<\/li>\n\n\n\n<li><strong>K\u2082SO\u2084 (potassium sulfate)<\/strong>: Upon dissolving, it dissociates into K\u207a and SO\u2084\u00b2\u207b ions. The K\u207a ion is neutral, and the sulfate ion (SO\u2084\u00b2\u207b) is the conjugate base of a strong acid (H\u2082SO\u2084), which also does not hydrolyze in water. Thus, K\u2082SO\u2084 solutions are neutral.<\/li>\n<\/ol>\n\n\n\n<p>In summary, only CH\u2083COONa forms a basic solution upon dissociation in water due to the hydrolysis of the acetate ion, which increases the hydroxide ion concentration in the solution.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Which of the following aqueous solutions will form a basic solution?a) AlCl\u207bb) NaBrc) CH\u2083COONad) K\u2082SO\u2084 The Correct Answer and Explanation is: The correct answer is c) CH\u2083COONa (sodium acetate).
