Determine the pH at the equivalence (stoichiometric) point in the titration of 27 mL of 0.24 M C6H5SH(aq) with 0.22 M NaOH(aq). The Ka of thiophenol is 3.2 x 10-7.

Respuesta :

Answer:

6.5 slightly acidic

Explanation:

pH =pka   -  log  [acid] / [base]

pH =6.49   -   log[0.224]/[0.22]

6.59-0.0377

6.45.
