CHM-122 Quiz #16 NAME: 1. The overall dissociation of malonic acid, H.C,H-Os, is represented below. The overal dissociation constant is also indicated To a 0.025-molar solution of malonic acid, a strong acid is added until the pH is 1.5.Calculate the ICaHi solution (Assume the change in volume is negigible.) K30x 10* resulting The value of the second dissociation constant, K 1 in the is 2.0x 10 ANSWER: 2. Determine the pH of a 2.25 M solution of pyridinium nitrate (CsHsNHNOs) at 25°C. (Pyridinium nitrate dissociates in water to give pyridinium ions (CsHsNH*), the conjugate acid of pyridine (Ko 1.73x 109), and nitrate ions (NOs) ANSWER:
