The ability of a base to dissociate completely into its ions determines whether it is classified as a strong base or a weak base.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>NaOH (Sodium Hydroxide):<\/strong> Sodium hydroxide is a strong base because it dissociates completely in water. The dissociation reaction is: NaOH\u2192Na++OH\u2212\\text{NaOH} \\rightarrow \\text{Na}^+ + \\text{OH}^-NaOH\u2192Na++OH\u2212 Since it dissociates fully, it is considered a strong base.<\/li>\n\n\n\n<li><strong>Ca(OH)2 (Calcium Hydroxide):<\/strong> Calcium hydroxide is also a strong base. It dissociates relatively well in water, although not as completely as sodium hydroxide. The dissociation reaction is: Ca(OH)2\u2192Ca2++2OH\u2212\\text{Ca(OH)}_2 \\rightarrow \\text{Ca}^{2+} + 2\\text{OH}^-Ca(OH)2\u200b\u2192Ca2++2OH\u2212 Despite the partial solubility in water, enough hydroxide ions are released to make it a strong base.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Why the others are not strong bases:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>AgOH (Silver Hydroxide):<\/strong> Silver hydroxide is a <strong>weak base<\/strong>. It is poorly soluble in water, and its dissociation does not proceed to completion. It tends to form a precipitate rather than dissociate fully into ions.<\/li>\n\n\n\n<li><strong>Pb(OH)2 (Lead(II) Hydroxide):<\/strong> Lead(II) hydroxide is also a <strong>weak base<\/strong>. Like AgOH, it is not very soluble in water and does not dissociate completely. It dissolves slightly in water and forms a solution with a very low concentration of hydroxide ions.<\/li>\n\n\n\n<li><strong>Mn(OH)2 (Manganese(II) Hydroxide):<\/strong> Manganese(II) hydroxide is another example of a <strong>weak base<\/strong>. It is slightly soluble in water and does not dissociate fully to release hydroxide ions.<\/li>\n<\/ul>\n\n\n\n<p>In summary, <strong>NaOH<\/strong> and <strong>Ca(OH)2<\/strong> are strong bases because they dissociate completely in water, while <strong>AgOH<\/strong>, <strong>Pb(OH)2<\/strong>, and <strong>Mn(OH)2<\/strong> are weak bases due to poor solubility and incomplete dissociation.<\/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-banner6-555.jpeg\" alt=\"\" class=\"wp-image-256051\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Select all of the following that are strong bases: NaOH Ca(OH)2 AgOH Pb(OH)2 Mn(OH)2 The strong bases among the options listed are: Explanation: Strong bases are substances that dissociate completely in water, releasing hydroxide ions (OH\u207b) to form a highly basic solution.
