When water donates a proton (H\u207a), it becomes hydroxide (OH\u207b), its conjugate base. The reaction can be written as:<br>[<br>H_2O \\rightarrow H^+ + OH^-<br>]<br>Here, H\u2082O donates a proton (H\u207a) to form OH\u207b, so H\u2082O is the acid and OH\u207b is the conjugate base.<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>HCO3\u207b is an acid and OH\u207b is its conjugate base:<\/strong><\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>This statement is incorrect because bicarbonate (HCO\u2083\u207b) is not donating a proton in this case. In fact, HCO\u2083\u207b can act as both an acid and a base, but it is not donating a proton to form OH\u207b. HCO\u2083\u207b would donate a proton to form CO\u2083\u00b2\u207b (carbonate), not OH\u207b.<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>H2O is an acid and HCO3\u207b is its conjugate base:<\/strong><\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>This is incorrect. H2O cannot donate a proton to form HCO3\u207b. In this context, HCO\u2083\u207b does not act as the conjugate base of H2O.<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>H2O is an acid and H2CO3 is its conjugate base:<\/strong><\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>This is incorrect because H2CO3 (carbonic acid) is not the conjugate base of H2O. In fact, H2CO3 would be a donor of a proton, not a product of H2O losing a proton.<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>HCO3\u207b is an acid and H2CO3 is its conjugate base:<\/strong><\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>This is incorrect because the conjugate base of H2CO3 is HCO3\u207b (not the other way around).
