    I would just mention that in buffers (by definition) all compounds are in the same solution, therefore you can work directly in moles rather than use concentrations.

    Wow, thank you for that. This will save me a lot of time in the future. So it's safe to plug in mole values into the Haselbalch formula? I usually tend to avoid it.

    I would seriously avoid using HH and simply use the non-log form of the dissociation equation.

    In your working there is no advantage to using logs.

    I see what you mean. I probably took it in logs because there was a given pH but in hindsight it was probably less work to directly use numbers. Thank you for all the help, though!
