Which species is the conjugate acid of HCO3-? <\/p>\n\n\n\n
A. CO32- <\/p>\n\n\n\n
B. H2CO3 <\/p>\n\n\n\n
C. CO2 <\/p>\n\n\n\n
D. H2O<\/p>\n\n\n\n
The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n The conjugate acid of ( \\text{HCO}_3^- ) (bicarbonate) is ( \\text{H}_2\\text{CO}_3 ) (carbonic acid). Therefore, the correct answer is B. ( \\text{H}_2\\text{CO}_3 )<\/strong>.<\/p>\n\n\n\n To understand why ( \\text{H}_2\\text{CO}_3 ) is the conjugate acid of ( \\text{HCO}_3^- ), we must first grasp the concept of conjugate acids and bases within the Br\u00f8nsted-Lowry acid-base theory. In this context, an acid is defined as a proton (H(^+)) donor, while a base is a proton acceptor. When an acid donates a proton, it transforms into its conjugate base; conversely, when a base accepts a proton, it becomes its conjugate acid.<\/p>\n\n\n\n In the case of bicarbonate, ( \\text{HCO}_3^- ) can act as a base. It has the ability to accept a proton (H(^+)) to form carbonic acid ( \\text{H}_2\\text{CO}_3 ). The chemical reaction can be represented as:<\/p>\n\n\n\n [ This process illustrates how bicarbonate accepts a proton, thereby becoming its conjugate acid.<\/p>\n\n\n\n Examining the other options:<\/p>\n\n\n\n Thus, the relationship between ( \\text{HCO}_3^- ) and ( \\text{H}_2\\text{CO}_3 ) highlights the fundamental principles of acid-base chemistry, with bicarbonate acting as a base that can accept a proton to become carbonic acid, its conjugate acid.<\/p>\n","protected":false},"excerpt":{"rendered":" Which species is the conjugate acid of HCO3-?
