In a titration, NaOH was added to a burette. The initial reading was 1.2 ml. At the end of the titration, the final reading was 24.8 ml. What was the volume of NaOH that was added?

Answer 1

You have two "addeds" in your post. I assume you want to know how much NaOH was ADDED FROM the buret TO the titration solution and not how much was added to the buret initially.
24.8-1.2 = ?
