I am reading an old paper and I have came to the passage shown in the picture:

k, C

I think I know what they did - they differentiated the first equation calculating dpH/dV and then took reciprocals of both sides of the equation. Is it a valid approach?

I am not able to get the same result solving the first equation for V and calculating dV/dpH then.

Bear in mind I am mathemathically challenged and English is my second language, I can be missing something obvious.

_{A}, C_{B}and V_{0}are all just some constants.I think I know what they did - they differentiated the first equation calculating dpH/dV and then took reciprocals of both sides of the equation. Is it a valid approach?
