Question

Suppose you had used the same flask for preparing the standard solution and the dilution. How would the concentration of the dilution have been affected if you had not rinsed the flask before using it again? Explain.

Answer 1

Answer:

Explanation:

We were told to rinse the buret with the base so that the concentration won't be messed up, but when it comes to the flask that is going to hold the acid, there is no need to rinse, because it would not affect the result if it has water in it.
