What is titration?
The term titration has to do with a reaction between an acid and a base to form salt and water only.
In this reaction, we have; KOH + HCl -----> KCl + H2O. The concentration of KOH was expressed to two significant figures.
The concentration of HCl is obtained from;
0.150 M * 18.5 mL * 1/25.0 mL * 1 = 0.11 M
