So, <strong>H\u2082S<\/strong> is the conjugate acid of <strong>HS\u207b<\/strong>.<\/p>\n\n\n\n<p>Here\u2019s a breakdown of the process:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>HS\u207b<\/strong> is a base because it has the ability to accept a proton.<\/li>\n\n\n\n<li>When <strong>HS\u207b<\/strong> accepts a proton (H\u207a), the result is <strong>H\u2082S<\/strong>, which is an acid because it can donate a proton in further reactions.<\/li>\n<\/ul>\n\n\n\n<p>It\u2019s important to distinguish this from the other options:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>A. S\u00b2\u207b<\/strong>: This is the conjugate base of <strong>HS\u207b<\/strong>. It would be formed if <strong>HS\u207b<\/strong> loses a proton, not gains one.<\/li>\n\n\n\n<li><strong>C. HS\u207b<\/strong>: This is the base we started with, so it cannot be its own conjugate acid.<\/li>\n\n\n\n<li><strong>D. S\u00b2\u207b<\/strong>: This is again the conjugate base of <strong>HS\u207b<\/strong> and is not relevant here.<\/li>\n<\/ul>\n\n\n\n<p>In summary, <strong>HS\u207b<\/strong> acts as a base, and its conjugate acid is <strong>H\u2082S<\/strong>. The conjugate acid of a base is always one proton (H\u207a) more than the base itself, and that&#8217;s why <strong>H\u2082S<\/strong> is the correct answer.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What is the conjugate acid of HS-?
