Hey everyone I had my chemistry exam today and there was a question I had issues with. Here it is:
A student took a sample of sulphuric acid from a large car battery spill near a park. A standard solution was prepared using sodium carbonate. 25mL of sulphuric acid was added to the burette. 25mL was pipetted from the standard solution and placed into a conical flask.
Now here is the interesting bit.
The student realized that the pipette was leaking during the transfer of the standard solution into the conical flask. What impacts will this have on the calculated concentration of sulphuric acid in comparison to its true concentration.
