Question
A volume of 25.0 mL of a 0.20 M unknown weak acid is titrated with 0.10 M NaOH.
After 15.0 mL base addition, the pH is measured at 2.92. Calculate the K of the
unknown acid. (Answer = 5.1 x 10)
Transcribed Image Text:A volume of 25.0 mL of a 0.20 M unknown weak acid is titrated with 0.10 M NaOH. After 15.0 mL base addition, the pH is measured at 2.92. Calculate the K of the unknown acid. (Answer = 5.1 x 10)
Expert Solution
Step 1: Gives values

Volume of weak acid (HA) = 25.0 ml

molarity of weak acid (HA) = 0.20 M

molarity of NaOH = 0.10 M

Volume of NaOH = 15.0 ml

pH = 2.92
