Question- A buffer was made by mixing 0.1488 moles of HCO2H with 0.1800 moles of NaHCO2 and diluting to exactly 1 liter. What will be the pH after addition of 10.00 mL of 0.2412 M RbOH to 50.00 mL of the buffer? Ka(HCO2H) = 1.800e-4. Note: only a portion of the original buffer is used in the second part of the problem.

Illustrate structures to prove your interpretation.
