Unformatted text preview: 6 H 5 OH (K a = 1.0 * 10 –10 )? [consider the last H to be acidic] 4. Solve for the K a of a weak acid, that when a solution 0.100 M of the weak acid is made, the resulting solution has a pH of 2.074. 5. Solve for the pH of a 0.250 M solution of (CH 3 ) 2 NH (K b = 5.9 * 10 –4 )...
