a buffer is made by mixing 0.1 moles of acetic acd a sodium acetate in 500 ml of solution. determine the pH of the buffer. (Ka for acetic acid - 1.8E-5)
Substitute into the Henderson-Hasselbalch equation and solve for pH. I think the answer ( I just did it in my head so be sure to confirm this) is 4.74.
