thanks for the help i really appreciate it :D

i know how to grapgh it and all i am only stuck with how to find the intial molar concentration. i believe you're telling me the step to finding the ka value. sorry i am a little confused with this
chemistry
the data is Vol. of NaOH added 0 1 2 3 4 5 10 15 20 21 22 23 24 25 26 27 28 29 30 35 40 45 50 pH 2.92 3.47 3.79 3.98 4.13 4.25 4.67 5.03 5.57 5.72 5.91 6.23 8.78 11.29 11.59 11.75 11.87 11.96 12.22 12.36 12.46 12.52 this is the data and this was given

so this is the question: you will be given a sample of nictinic acid with an unknown concentration, and it will be titrated with 0.100M NaOH. instead of measuring the volume of the basic solution required to reach the endpoint, however, you will measure the pH. Then you will g...

the chemical equation of nicotinic acid is C5H4NCOOH + NaOH --> C5H4NCOONa + H2O i need to calculate the intial molar concentration of this acid, based on the ratio in which the acid and base react. Please help i cant figure it out,
