Question

So long as the conical flask is clean why does it not matter if it is wet prior to addition of the 𐑃-ascorbic acid solution? 1. it does matter, it is essential to the experiment that all equipment is clean and dry before use 2. because water does not t

Answer 1

It depends on what you are doing - sometimes stuff needs to be dry....other times its ok if its wet.

Explanation:

For example, if you are going to add your ascorbic acid solution to a conical flask, and then dilute to a certain volume, it doesn't matter if they flask is wet/dry. Either way will be ok (since you'll be adding water to a specific mark anyway).

If you are weighing something, then it obviously needs to be dry.

If you are putting the ascorbic acid solution into a conical flask to do an experiment with it, then it definitely needs to be dry, since the water in the flask will change the volume slightly, and this will change the concentration.

So it all depends.
