The concentration of acetic acid:
The concentration of the acetic acid before titration is 0.128 M
What is titration?
Titration is a quantitative analytical procedure that works by allowing a known analyte to gradually react with a titrant until an endpoint is reached.
Titration for weak acid and strong base:
Moles of acetic acid = moles of NaOH
Given:
Concentration of NaOH = 0.1067 M
Volume of NaOH = 30.07 ml = 0.03007 L
Calculation:
So, by using the formula, Concentration = Moles/Volume
Moles of NaOH = concentration x volume = 0.1067 x 0.03007 = 0.0032
Therefore, the moles of acetic acid = 0.0032 mole
Now, using the formula again for determining the concentration of acetic acid, we get,
Concentration = Moles/Volume
Concentration of acetic acid = 0.0032/0.025 = 0.128M
