Question 40 POST_UTME_BSU • 2017 • CHEMISTRY • objective

A 0.1 M solution of NaOH is titrated with 0.1 M HCl. If the initial pH is 12, calculate the pH after 10 mL of HCl has been added.

A. \( pH = \frac{1}{2} left\( pH_0 + pH_f \right \ \) )

Correct Answer B. \( pH = \frac{1}{2} left\( pH_0 + pH_f \right \ \) \times \frac{V}{V_0} )

C. \( pH = \frac{1}{2} left\( pH_0 + pH_f \right \ \) \times \frac{V}{V_0} \times \frac{C}{C_0} )

D. \( pH = \frac{1}{2} left\( pH_0 + pH_f \right \ \) \times \frac{V}{V_0} \times \frac{C}{C_0} \times \frac{t}{t_0} )

Correct Answer

Correct Option:

\( pH = \frac{1}{2} left\( pH_0 + pH_f \right \ \) \times \frac{V}{V_0} )
