Answer : The mass of sodium acetate is, 1.097 grams.
Explanation : Given,
The dissociation constant for acetic acid =
Concentration of acetic acid (weak acid)= 0.20 M
volume of solution = 125. mL
pH = 4.47
First we have to calculate the value of .
The expression used for the calculation of is,
Now put the value of in this expression, we get:
Now we have to calculate the concentration of sodium acetate (conjugate base or salt).
Using Henderson Hesselbach equation :
Now put all the given values in this expression, we get:
Now we have to calculate the mass of sodium acetate.
Therefore, the mass of sodium acetate is, 1.097 grams.
