Calculate the pH of the solution formed when 45.0 mL of 0.100M NaOH solution is added to 50.0 mL of 0.100M CH3COOH (Ka for aceti
pav-90 [236]

Answer:

pH of soltion will be 5.69

Explanation:

The pH of the solution will be due to excessive acid left and the salt formed. Thus, it will form a buffer solution.

The pH of buffer solution is calculated from Henderson Hassalbalch's equation, which is:

pH=pKa+log(\frac{[salt]}{[acid]} )

pKa=-log(Ka)

pKa=-log(1.8X10^{-5})=4.74

The moles of acid taken :

moles=molarityXvolume=0.1X50=5mmol

The moles of base taken:

moles=molarityXvolume=0.1X45=4.5mmol

The moles of acid left after reaction :

5-4.5=05mmol

The moles of salt formed = 4.5mmol

Putting values in equation

pH=pKa+log(\frac{[salt]}{[acid]} )=4.74+log(\frac{4.5}{0.5})=5.69
