Sorry that this is kind of a specific thread, but I really wanted help with this kind of problem and our professor never showed us how to do it, and this other girl who thought she knew how to do it got it wrong, and it's guaranteed to be on the test in some way/shape/form.
It's a buffer calculation.
Calculate the pH of a buffer solution composed of 1.0L of 0.50M formic acid (HCO2H) and 0.60M sodium formate (NaHCO2) before and after adding 0.01 mol NaOH (solid). (Ka = 1.0 x 10^-5).
pH before?
pH after?
I know how to calculate pH but he never explained what to do if we change concentrations of things or add stuff with buffer solutions.
If anyone could help me, that would be wonderful! Thank you!
