Question

a buffer solution contains 0.1M of acetic acid and 0.1M of sodium acetate(a 0.2M acetate buffer). What is the ph after 4 ml of a 0.05M HCl are added to 10 ml of the buffer (Ka=1.8*10-5)​

Answer 1

Answer:

Explanation:

So log(Salt/Acid)= 5.4–4.7447= 0.6553 . Therefore if the concentration of CH3-COONa is 4.522- times that of Acetic acid then the pH of the buffer will be =5.4.
