Question

G. A student did not read the directions to the experiment properly and mixed up where to place the NaOH solution and the vinegar. He put the vinegar in the titrator and the measured amount of NaOH in the beaker. He then added a drop of the phenolphthalein to the solution in the beaker. Does the student need to empty out all of the solutions and start over again or can he go ahead and run the titration? If he runs the titration using the solutions as given above, what should he expect to see happen for results?

Explanation / Answer

Yes, the student have to start the experiment again because for thr calculation purpose it is important to use as much as NaOH that is needed. If vinegar is added to NaOH then the ratio would get change (approximately it will get flipped) and the color of the solution would most likely become pink.
