The conjugate base of HCO3- is CO32-. Conjugates always differ by one H+. A conjugate base has one fewer H+, while a conjugate acid has one more H+. View this answer. The conjugate base of HCO 3 - is CO 3 -2, which is the carbonate ion. To determine the conjugate base of a substance, you remove one hydrogen ion. It's... See full answer below. A conjugate acid is a substance that is formed when a base receives a proton, or H^(+). So, in order to determine the conjugate acid for a given base, all you have to know is that "base" + H^(+) -> "conjugate acid of that base" In your case, the base is hydrogen carbonate, or HCO_3^(-). Conjugate Acids and Bases: Weak acids have a conjugate base and vice versa. You can determine the conjugate acid by adding a proton to the conjugate base. The conjugate base of an acid is just the acid with one less hydrogen atom and the charge decreases by one. Acid Conjugate Base HBr Br - H2CO3 HCO3 - HClO4 ClO4 - HC2H3O2 C2H3O2 - NH3 NH2 - HSO4 -... acid base base acid. here H2CO3 and HCO3- are conjugate acid-base pair as are H2O and OH-b) HCl + H 2 PO 4-<-----> Cl - + H 3 PO 4. HCl transfers a proton (H+ ion) to H 2 PO 4- and form Cl - and H 3 PO 4, now Cl - can accept a proton donated by H 3 PO 4 .so the above equation is; Answered 2011-04-27 08:58:37. The conjugate base of HCO3- is CO32-. Conjugates always differ by one H+. A conjugate base has one fewer H+, while a conjugate acid has one more H+. 0 0 1. 🙏🏿. Explanation. What is the conjugate base of HCO3-? Answer. The conjugate base of bicarbonate, HCO 3- is carbonate, CO3 2-. HCO3- is a conjugate acid, H 2 CO 3. Log in or register to post comments. Identify the conjugate acid of CO 3 2– and the conjugate base of HSO 4 – in the following reaction: HSO 4 – (aq) + CO 3 2– (aq) ⇌ HCO 3 – (aq) + SO 4 2 – (aq) a. H 2 CO 3 and H 2 SO 4 b. HCO 3 – and SO 4 2 – c. HCO 3 – and H 2 SO 4 d. H 2 CO 3 and HSO 4 – e. none of the above The conjugate acid and conjugate base of bicarbonate ion (HCO3–) are, respectively, A. CO32– and OH–. B. H2CO3 and CO32–. C. H3O+ and CO32–. D. H2CO3 and OH–. E. H3O+ and OH–.
