3. a student titrated 25.00 ml of a solution of formic acid with sodium hydroxide of known concentration. the student plotted ph verses volume (ml) of naoh added and found that the titration required 26.66 ml of naoh to reach equivalence point. describe how you would use the students’ titration curve to determine the concentration of the formic acid solution.

If 42.1 ml of 1.02 m sodium hydroxide, measured using a graduated cylinder, is placed in a beaker filled with 300 ml of di water, what is the concentration of the diluted naoh solution? b) why does this calculation only provide an estimate of the naoh concentration? in other words, why do we have to standardize the naoh in this experiment to find its exact concentration?
