In this case, <strong>phosphoric acid (H\u2083PO\u2084) reacts with potassium hydroxide (KOH)<\/strong>. Phosphoric acid is a <strong>triprotic acid<\/strong>, meaning it has three hydrogen ions (H\u207a) available to donate. Potassium hydroxide is a <strong>strong base<\/strong>, which means it dissociates completely in water to release hydroxide ions (OH\u207b).<\/p>\n\n\n\n<p>The reaction proceeds as follows:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>H\u2083PO\u2084 donates protons (H\u207a), acting as an acid.<\/strong><\/li>\n\n\n\n<li><strong>KOH provides hydroxide ions (OH\u207b), which act as a base.<\/strong><\/li>\n\n\n\n<li>The H\u207a from the acid combines with OH\u207b from the base to form water ((H_2O)).<\/li>\n\n\n\n<li>The remaining phosphate ions (PO\u2084\u00b3\u207b) combine with potassium (K\u207a) to form potassium phosphate ((K_3PO_4)), a soluble salt.<\/li>\n<\/ol>\n\n\n\n<p>This reaction is classified as a <strong>neutralization reaction<\/strong>, a fundamental acid-base interaction in chemistry. The complete neutralization of <strong>one molecule of phosphoric acid<\/strong> requires <strong>three molecules of KOH<\/strong> because <strong>each KOH provides one OH\u207b ion, and H\u2083PO\u2084 has three protons to neutralize<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Conclusion<\/strong><\/h3>\n\n\n\n<p>The role of the reagent depends on which substance you consider:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>H\u2083PO\u2084 is the acid<\/strong> because it donates H\u207a.<\/li>\n\n\n\n<li><strong>KOH is the base<\/strong> because it provides OH\u207b.<\/li>\n\n\n\n<li><strong>In this context, the acid-base roles are more relevant than nucleophilic or electrophilic behavior<\/strong>.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>A.
