Question

Suppose another student misses the endpoint in the titration by adding far too much NaOH. Will her % Co be high or low? Explain.

Answer 1

will depending on the Test method employed.

Suppose for any titration, if we miss the end point , means we have added more solution from burett. So to determine the end point of the sample , then again we have to add the primary standared solution drop by drop, which we have taken in the conical flask , then we can measure the quantity of solution excee we have added.

Let's assume the following scenarios:

1. Back Titration: It will be a low cobalt %
2. Direct Titration: It will be a high cobalt %
