Question

5. An aqueous solution containing (2.3x10^-1) M of a generic acid, HA, has a pH of 3.29. What is the Ka for this acid?

HINT: Set up an ICE table, and use the pH value to determine X and solve for Ka!

In the appropriate blanks, provide the acid dissociation constant, Ka, for this acid (HA). Report the value to two significant figures and to the appropriate power (e.g. Write only the values, e.g. 5.1x10-3do not write anything else).
