Barium hydroxide, Ba(OH)\u2082, is a strong base that completely dissociates in water into barium ions (Ba\u00b2\u207a) and hydroxide ions (OH\u207b). Similarly, hydrochloric acid, HCl, is a strong acid that completely dissociates into hydrogen ions (H\u207a) and chloride ions (Cl\u207b).<\/p>\n\n\n\n<p><strong>Step 1: Write the dissociation of the reactants<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Ba(OH)\u2082(aq) \u2192 Ba\u00b2\u207a(aq) + 2OH\u207b(aq)<\/li>\n\n\n\n<li>2HCl(aq) \u2192 2H\u207a(aq) + 2Cl\u207b(aq)<\/li>\n<\/ul>\n\n\n\n<p><strong>Step 2: Combine the ions to form the complete ionic equation<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Ba\u00b2\u207a(aq) + 2OH\u207b(aq) + 2H\u207a(aq) + 2Cl\u207b(aq)<\/li>\n<\/ul>\n\n\n\n<p><strong>Step 3: Determine the products<\/strong><br>In an acid-base reaction, the hydroxide ions (OH\u207b) from the base react with the hydrogen ions (H\u207a) from the acid to form water:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>2OH\u207b(aq) + 2H\u207a(aq) \u2192 2H\u2082O(l)<\/li>\n<\/ul>\n\n\n\n<p>The chloride ions (Cl\u207b) and barium ions (Ba\u00b2\u207a) remain in the solution as spectator ions.

Note that the barium and chloride ions are spectator ions because they do not participate directly in the formation of the water.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner6-637.jpeg\" alt=\"\" class=\"wp-image-256506\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Balance the complete ionic equation when aqueous barium hydroxide reacts with aqucous hydrochloric acid The Correct Answer and Explanation is: Correct Answer: The balanced complete ionic equation is: Ba\u00b2\u207a(aq) + 2OH\u207b(aq) + 2H\u207a(aq) + 2Cl\u207b(aq) \u2192 Ba\u00b2\u207a(aq) + 2Cl\u207b(aq) + 2H\u2082O(l) Explanation: When aqueous barium hydroxide reacts with aqueous hydrochloric acid, a neutralization reaction occurs.
