A buffer contains 0.16 mol of propionic acid (C2H5COOH) and 0.16 mol of sodium propionate (C2H5COONa)...
A buffer contains 0.16 mol of propionic acid (C2H5COOH) and 0.16 mol of sodium propionate (C2H5COONa) in 1.20 L.
a) What is the pH of this buffer?
b)What is the pH of the buffer after the addition of 0.01 mol of NaOH? (I got 4.77 the first time but it's not correct and im not sure why)
c) What is the pH of the buffer after the addition of 0.01 mol of HI?
Can you please include a step by step procedure of how to answer these questions? Thank you!
