Titration. Acid–Base Titration. The concentration of a weak acid or a weak base in water is difficult – if not impossible – to measure directly.. But we can calculate the concentration from the results of titration.. What did one titration tell the other?  . Let's meet at the endpoint.. Why are chemists great for solving problems?   . They have all the solutions. Titration. A lab procedure by which the concentration of acidic or alkaline solutions are examined and determined. Titration of a Strong Acid by a Strong Base. Consider what happens to the pH of 25 mL of 0.2 M . HCl. as it is titrated with 25 mL of 0.2 M . NaOH. . This result is shown in the diagram to the right.
