How to calculate the pH of a buffer after HCl was added?

WebYou want to produce a CH3COOH /CH3COONa buffer with pH = 5.00 . What is the ratio of conjugate base to acid? You start by using the Henderson - Hasselbalch equation: pH = pKa + log ( [CH3COONa]/ [CH3COOH] pKa = - log (1.8*10^-5) = 4.74 5.00 = 4.74 + log ( [CH3COONa]/ [CH3COOH] log ( [CH3COONa]/ [CH3COOH] = 5.00–4.74 WebNow, you can see that sodium hydroxide and acetic acid react in a 1:1 mole ratio. This means that we need the same number of moles of NaOH as we have CH3COOH for a complete reaction. Using concentration and volume we can determine the #mol of NaOH used: n (NaOH) = CV = (0.0500 mol/L) (0.0150 L) = 7.50×10^-4 mol NaOH. how does the author introduce her thesis https://redrockspd.com
