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?
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 = ?
To find the volume of NaOH that was added during the titration, you need to subtract the initial reading from the final reading on the burette.
In this case, the initial reading was 1.2 ml and the final reading was 24.8 ml.
So, the volume of NaOH that was added can be calculated as:
Volume of NaOH = Final reading - Initial reading
= 24.8 ml - 1.2 ml
= 23.6 ml
Therefore, the volume of NaOH that was added during the titration is 23.6 ml.
