Hcho2 dissociation equation
WebHCHO2(ag), a weak acid (K, = 2 x10), dissociates in water according to the equation above. Which of the following provides the best estimate of the pH of 0.5 M HCHO2(aq) and identifies the species at the highest concentration (excluding H2O) in the solution? WebIn the Brønsted–Lowry definition of acids and bases, a conjugate acid–base pair consists of two substances that differ only by the presence of a proton (H⁺). A conjugate acid is formed when a proton is added to a base, and a conjugate base is formed when a proton is removed from an acid. Created by Yuki Jung. Sort by:
