Its chemical formula is C\u2088H\u2085KO\u2084, and it consists of a phthalate group (C\u2088H\u2085O\u2084) with a potassium ion (K\u207a) and a hydrogen atom (H\u207a) attached. In solution, KHP dissociates into K\u207a and the phthalate anion (C\u2088H\u2085O\u2084\u207b).<\/li>\n\n\n\n<li><strong>NaOH (Sodium Hydroxide)<\/strong> is a strong base, meaning it dissociates completely in water into Na\u207a and OH\u207b ions.<\/li>\n<\/ol>\n\n\n\n<p>In this reaction, the hydroxide ion (OH\u207b) from NaOH reacts with the hydrogen ion (H\u207a) from KHP, forming water (H\u2082O). The phthalate anion (C\u2088H\u2085O\u2084\u207b) then combines with the sodium ion (Na\u207a) from NaOH to form sodium phthalate (C\u2088H\u2085NaO\u2084).<\/p>\n\n\n\n<ol start=\"3\" class=\"wp-block-list\">\n<li><strong>Balancing the equation<\/strong>: The equation is balanced in terms of atoms and charges. On the left side, KHP contributes a potassium ion (K\u207a) and a phthalate ion (C\u2088H\u2085O\u2084\u207b), and NaOH contributes sodium (Na\u207a) and hydroxide (OH\u207b). On the right side, the potassium ion (K\u207a) and sodium ion (Na\u207a) are associated with their respective counterions (phthalate and hydroxide), and water is formed from the reaction of H\u207a and OH\u207b. Since each side contains 8 carbon atoms, 5 hydrogen atoms, 4 oxygen atoms, 1 sodium atom, and 1 potassium atom, the equation is balanced.<\/li>\n\n\n\n<li><strong>Significance in titration<\/strong>: This reaction is often used in acid-base titrations, where KHP is used as a primary standard to determine the concentration of a sodium hydroxide solution.
