Sodium carbonate is made of two sodium ions (<strong>Na\u207a<\/strong>) and one carbonate ion (<strong>CO\u2083\u00b2\u207b<\/strong>).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Dissociation Process:<\/h3>\n\n\n\n<p>The chemical formula of sodium carbonate indicates that it contains two sodium atoms and one carbonate group. Upon dissolving in water, the dissociation can be represented by the following balanced chemical equation:<\/p>\n\n\n\n<p><strong>Na\u2082CO\u2083 (s) \u2192 2Na\u207a (aq) + CO\u2083\u00b2\u207b (aq)<\/strong><\/p>\n\n\n\n<p>Here is what happens step by step:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Sodium ions (Na\u207a)<\/strong> are <strong>monovalent cations<\/strong>, meaning each carries a <strong>+1 charge<\/strong>. In sodium carbonate, there are two of these to balance the charge of the anion.<\/li>\n\n\n\n<li><strong>Carbonate ion (CO\u2083\u00b2\u207b)<\/strong> is a <strong>polyatomic anion<\/strong> with a <strong>-2 charge<\/strong>. It consists of one carbon atom covalently bonded to three oxygen atoms, and the whole ion carries a 2\u2212 charge.<\/li>\n<\/ol>\n\n\n\n<p>The charges must balance to make the original compound neutral. That is why two Na\u207a ions (each +1) balance the single CO\u2083\u00b2\u207b ion (\u22122).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Nature of the Ions in Solution:<\/h3>\n\n\n\n<p>In solution:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Na\u207a ions<\/strong> remain freely hydrated in water. They do not hydrolyze and are considered neutral in acid\u2013base terms.<\/li>\n\n\n\n<li><strong>CO\u2083\u00b2\u207b ions<\/strong> can react with water in a process known as hydrolysis, where they accept hydrogen ions (protons) from water to form <strong>HCO\u2083\u207b (bicarbonate ion)<\/strong> and <strong>OH\u207b (hydroxide ion)<\/strong>. This gives sodium carbonate a <strong>basic<\/strong> character in solution.<\/li>\n<\/ul>\n\n\n\n<p>In summary, the ions present in a sodium carbonate solution are <strong>Na\u207a<\/strong> and <strong>CO\u2083\u00b2\u207b<\/strong>, reflecting complete dissociation in aqueous media.<\/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-banner8-924.jpeg\" alt=\"\" class=\"wp-image-37584\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-924.jpeg 852w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-924-250x300.jpeg 250w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-924-768x923.jpeg 768w\" sizes=\"auto, (max-width: 852px) 100vw, 852px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Write the ions present in a solution of Na2CO3.
