This tool is invaluable for educational purposes, allowing for rapid answers and To find the conjugate base, just remove the H. Aqueous solutions of HI are known as hydroiodic acid or hydriodic acid, a strong acid. When identifying conjugate acid-base pairs, they must differ in the presence of one proton (H⁺). 5 Conjugate Acid-Base Pairs As you ponder the Brønsted-Lowry theory of acids and bases there are some important things to think about. We argued Question: Write the formula of the conjugate base of each acid: HI, HCO3 , and CH3CH2OH. A conjugate base is created upon a proton loss by its respective acid, while acceptance of a proton by a base creates the conjugate acid. This foundational concept in chemistry supports the identification of HI and I− as the acid Bronsted-Lowry Acid-Base Theory: To define if a given pair is a conjugate acid-base pair, we need to define first what is an acid or base using the Bronsted-Lowry acid-base theory. The conjugate The chemical formula for hydroiodic acid is HI. This is because HI donates a proton to water, forming I⁻ as the conjugate base. Hydrogen iodide and hydroiodic acid are, however, different in that the former is a gas under standard conditions, whereas the latter is an aqueous solution of the gas. However, it readily dissolves in water, forming a solution of hydroiodic Objectives After completing this section, you should be able to state the Brønsted-Lowry definition of an acid and a base.

Treat the conjugate acid of a base as an acid in numerical calculations. One of the more useful aspects of the Brönsted-Lowry definition of acids and bases in helping us deal with the pH of solutions is the concept of the conjugate acid-base pair. When one of these acids dissolves in water, their protons are completely transferred to water, the stronger base. When HI dissociates, it forms a proton and an iodide anion. The best free online Cambridge International A-Level resource trusted by students and 1. Reverse the role of acid and base Conjugate acid-base pairs are related through the gain and loss of a proton. When HI loses a proton, it forms I⁻, which is a common example of a binary acid dissociating into its conjugate base. It can spread negative The acid-conjugate base pair in the reaction HI + H2O → H3O+ + I− is D. NH4+ is the conjugate acid to the base NH3, because NH3 gained a hydrogen ion to form NH4+.
