Determination of Ka and Identification of an Unknown Weak Acid Post-lab Question 1. Suppose that a student performing this experiment mistakenly calibrated the pH meter using pH 8 buffer instead of pH 7 buffer. As a result of this error, all of the student's pH readings were too low. a) Would this error have affected the calculated molar mass of the unknown acid? Briefly explain. b) Would this error have affected the experimentally determined pKa of the unknown acid? Briefly...

When dealing with buffer systems, we often use the acid reaction to determine the equilibrium and set up the ICE table. The most common experimental method used to study acid-base systems is titration, which studies the stoichiometric addition of the acid to a base solution or the base to an acid solution to determine the value of K, or K, The value of the pK, or pK, is essential to the understanding of the buffer system, where pK, = -log...
