Calculating [H1] and pKa from the pH of a Solution of Weak Acid The pH of a 0.02 M solution of an acid was measured at 4.6. a. What is the [H+] in this solution? b. Calculate the acid dissociation constant Ka and pKa for this acid.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
