2. A 25.00 mL sample of an unknown monoprotic weak acid is titrated to the equivalence point
with 14.65 mL of 0.09861 M NaOH. Calculate the concentration of the unknown weak acid.
Solution
at equalent point no of moles of weak acid = no of moles of base
M1V1 = M2V2
HA is mono protic acid
HA + NaOH ---------------> NaA + H2O
HA NaOH
M1 = M2 = 0.09861M
V1 = 25ml V2 = 14.65ml
M1V1 = M2V2
M1 = M2V2/V1
= 0.09861*14.65/25 = 0.058 M
The concentration of the unknown weak acid is 0.058M
