It also shows you how to identify conjugate acid base Answer to: What is the conjugate base for HNO3? By signing up, you'll get thousands of step-by-step solutions to your homework questions. The simplest anion which can be a conjugate base Additionally, in neutralization reactions, NO3- will often react with other positively charged ions to form salts, demonstrating its role as a conjugate base. If this problem persists, tell us. H2O acquires the H+ ions most of the time, as we Furthermore, because nitric acid, HNO3, loses a proton, H +1, to generate its conjugate in the reaction that is shown above, this reactant can be classified as a Brønsted-Lowry acid, and, consequently, H2O is the strongest base. The removal of the hydrogen ion, which is the same as a proton, makes the See full answer below. Therefore, the formula for the conjugate acid of nitrate (NO3⁻) is: HNO3 CLAS * Compiled from Appendix 5 Chem 1A, B, C Lab Manual and Zumdahl 6th Ed. Strong acids, such as HNO3 have weak conjugate bases, so NO3 - is a weak base. It is the The conjugate acid of a base is formed by adding a proton (H+) to the base.
