Use the Acid-Base Table to write net equations and determine the equilibrium constants for the Bronsted acid-base reactions that occur when aqueous solutions of the following are mixed. Substances Acid(1) + Base(2) -> Base(1) + Acid(2) K HC2H3O2 + Na2HPO4 KNO2 + HIO3 HF + KClO
Write the net equations and determine the equilibrium constants for the acid-base reactions that occur when aqueous solutions of the following are mixed. (Use the lowest possible coefficients. Omit states-of-matter in your answer. Your reaction arrow may be either a right arrow (-->) or an equilibrium arrow (<=>), depending upon the value of Keq for the reaction. Use the Acid/Base Table. (a) acetic acid (CH3COOH) and ammonia, K= (b) hydrochloric acid and sodium hydroxide (Please write the conjugate acid and...
Use the Acid-Base Table to write net equations and to determine the equilibrium constants for the Bronsted acid-base reactions that occur when aqueous solutions of the following are mixed.

Writing Proton-Transfer Equations for Acid-Base Reactions •PROBLEM: Write balanced total and net ionic equations for the following reactions and use curved arrows to show how the proton transfer occurs. –(a) hydriodic acid (aq) + calcium hydroxide (aq) → Give the name and formula of the salt present when the water evaporates. –(b) potassium hydroxide (aq) + propionic acid (aq) → Note that propionic acid is a weak acid. Be sure to identify the spectator ions in this reaction.
During lab you measured the pH of mixtures containing strong acid and strong base. Write net Brønsted equations that show the acid-base reactions of common household items. For polyprotic species (such as vitamin C, lemon juice, and washing soda), please show only one proton transfer. Remember that spectator ions are not included. (Use the lowest possible coefficients. Omit states-of-matter in your answer.) (a) bleach and vinegar (sodium hypochlorite and HC2H3O2) (b) bleach and Vitamin C (sodium hypochlorite and H2C6H6O6)
