For #1, would I have to multiply 500 mL to 0.050 moles and 0.20 moles? Or can I just set it up like this below and solve for it? pH=4.75 + log [0.20]/[0.050]
Would HCL be put on the bottom with HF because it's an acid also?
Thank you so much!
For the formula pH=pka + log(base/acid) Which would be the base and which would be the acid? Thanks.
