(Please show work)

A 100.0 mLbuffer solution is 0.250 M in acetic acid (CH3COOH) and 0.250 M in sodium acetate (CH3COONa). [Acetic Acid (CH3COOH) Ka = 1.8 x 10-5]

a)What is the pH of this buffer solution?

b)What is the pH after addition of 0.0050 mol of HCl?

c)What is the pH after addition of 0.0050 mol of NaOH?

Answer 1

Answer #1

MoxMixt is an example for acidic buffer

And added acid reacts with salt and forms acid hence acid concentration increases and salt concentration decreases. PH slightly decreased.

Added base reacts with acid and forms salt and acid concentration decreases hence pH slightly Increases
