16.25 ml NaOH was used for the titration.
"The process of calculating the quantity of a material A by adding measured increments of substance B, the titrant, with which it reacts until exact chemical equivalency is obtained (the equivalence point)" is the definition of titration.
A titration is a method for figuring out the concentration of an unknown solution by using a solution with a known concentration. Until the reaction is finished, the titrant (the known solution) is typically added from a buret to a known volume of the analyte (the unknown solution).
0. 010 m NaOH is the titrant (in the buret).
The initial buret reading is 2. 45 ml
The final buret reading is 18. 70 ml
The volume of NaOH = 18.70ml - 2.45 ml
= 16.25 ml
Therefore, 16.25 ml NaOH was used for the titration.
