Analytical Chemistry
If an acid has a Ka value of 1.0 x 10-5, what is its pKa value?
What is the principal species in a solution of acetic acid (pKa = 4.76) at pH 3?
What is the distribution of acid and base forms when pH equals pKa?
Which statement best describes a zwitterion at the isoelectric point?
Given the pKa values of aspartic acid as 2.1, 3.9, and 9.8, calculate its isoelectric point.
How would you calculate the pH at the isoionic point of a diprotic acid with pKa1 = 4.0 and pKa2 = 8.0?
