What mass of sodium hydroxide must be added to 25.0 mL of 0.126 M acetic acid in order to create a buffer with a pH of 4.90? Ka for acetic acid is 1.8 × 10-5.
(a) 0.000013 g
(b) 0.074 g
(c) 0.13 g
(d) 57 g
(e)1.0 g
I'm not at all sure how to solve this problem. I think I may have to use the Henderson-Hasselbach Equation, but I'm not sure what values, etc. I have to use (whether or not I need to use the ICE method first)Can someone please explain to me how you go about solving this problem? Thanks in advance
