      Explanation (300 words)<\/strong><\/h3>\n\n\n\n

      Acids and bases are classified according to the Bronsted-Lowry theory<\/strong>, which defines acids as proton (H\u207a) donors and bases as proton acceptors. Every acid has a corresponding conjugate base, which is formed after the acid donates a proton. Similarly, every base has a conjugate acid, which is formed when the base gains a proton.<\/p>\n\n\n\n

      For example, ammonium ion (NH\u2084\u207a) acts as an acid<\/strong> because it donates an H\u207a to form ammonia (NH\u2083), which is its conjugate base<\/strong>. In water, H\u2082O can act as either an acid or a base<\/strong>. When H\u2082O donates a proton, it forms hydroxide (OH\u207b), which is its conjugate base<\/strong>. On the other hand, when H\u2082O accepts a proton, it forms H\u2083O\u207a, which is its conjugate acid<\/strong>.<\/p>\n\n\n\n

      Sulfuric acid (H\u2082SO\u2084) is a strong acid<\/strong>, meaning it fully dissociates in water to release protons. Its conjugate base is sulfate ion (SO\u2084\u00b2\u207b), which is formed after H\u2082SO\u2084 loses protons.<\/p>\n\n\n\n

      Understanding these concepts is crucial in acid-base chemistry, as it helps explain reactions such as neutralization, buffer solutions, and pH regulation in biological systems. For example, the bicarbonate (HCO\u2083\u207b) system in blood acts as a buffer, maintaining pH balance by shifting between carbonic acid (H\u2082CO\u2083) and bicarbonate (HCO\u2083\u207b) depending on the body’s needs.<\/p>\n\n\n\n

      By recognizing acids, bases, and their conjugate pairs, we can predict reaction directions, buffer capacities, and chemical equilibrium in various environments.<\/p>\n","protected":false},"excerpt":{"rendered":"
