Question

Errors occurring during experimental titration cause errors in the final answer. A student stops the titration when the pink color appears and then disappears after two seconds of swirling. What effect does this have on the calculated concentration of acetic acid in the vinegar? The calculated concentration is higher than the actual real concentration. The calculated concentration is lower than the actual real concentration. The calculated concentration is accurate. The calculated concentration cannot be determined.

Explanation / Answer

If pink color disppears after some time indicates that there is still some amount of acid is left in the titration process.So, then the calculated concentration of acetic acid is lower than the actual real concentration.
