It dissociates completely in water to release hydroxide ions (OH\u207b), making the solution strongly alkaline. Although it\u2019s not as soluble as other strong bases (like sodium hydroxide), its dissociation in water is significant enough to classify it as a strong base.<\/li>\n\n\n\n<li><strong>H2CO3, strong acid<\/strong> \u2013 <strong>Incorrect<\/strong>: Carbonic acid (H2CO3) is a weak acid. It partially dissociates in water to release hydrogen ions (H\u207a) and bicarbonate ions (HCO\u2083\u207b). Since it doesn\u2019t dissociate completely, it is classified as a weak acid, not a strong acid like hydrochloric acid (HCl).<\/li>\n\n\n\n<li><strong>NaOH, strong base<\/strong> \u2013 <strong>Correct<\/strong>: Sodium hydroxide (NaOH) is a strong base. It dissociates completely in water to release sodium ions (Na\u207a) and hydroxide ions (OH\u207b), making the solution highly alkaline. Strong bases, like NaOH, have high dissociation in water, resulting in a large concentration of OH\u207b ions.<\/li>\n\n\n\n<li><strong>HCl, weak acid<\/strong> \u2013 <strong>Incorrect<\/strong>: Hydrochloric acid (HCl) is a strong acid. It dissociates completely in water, releasing hydrogen ions (H\u207a) and chloride ions (Cl\u207b). Strong acids, such as HCl, fully ionize in aqueous solution, making them highly effective at increasing the concentration of H\u207a ions in solution.<\/li>\n\n\n\n<li><strong>NH3, strong acid<\/strong> \u2013 <strong>Incorrect<\/strong>: Ammonia (NH3) is not an acid; it is a weak base. When ammonia dissolves in water, it accepts a proton (H\u207a) to form ammonium ions (NH\u2084\u207a) and hydroxide ions (OH\u207b), making the solution basic. Therefore, it is classified as a weak base, not a strong acid.<\/li>\n<\/ol>\n\n\n\n<p>In summary, the only correct identification is <strong>NaOH as a strong base<\/strong>, while the others are either incorrectly identified or misclassified.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Which of the following is correctly identified?Ca(OH)2, weak baseH2CO3, strong acidNaOH, strong baseHCl, weak acidNH3, strong acid The Correct Answer and Explanation is : The correct identification in the list is NaOH, strong base.
