Answer to Question #48442 in Inorganic Chemistry for ami
Use Hess’ Law to show how the titration of acetic acid with sodium hydroxide can be expressed as the combination of two reactions: the acetic acid reacting with water, and the sodium hydroxide reacting with hydronium ion. Calculate the value of the equilibrium constant (Kc) for the reaction of acetic acid with sodium hydroxide. What is the significance of the value of Kc in this case? E. Calculate the pH of a 0.75 M acetic acid solution, CH3COOH, Ka = 1.8 x 10–5, and compare it with the calculated pH of a 0.75 M diethylamine solution, (CH3CH2)2NH, Kb = 7.1 x 10–4. What is the ratio of the hydronium ion concentrations in each solution?
