How does distilled water affect the molarity/concentration in a titration?
We did a lab in my chem class and I'm really confused on this question. If you rinsed the buret with distilled water before the titration how would that end up affecting the molarity of the solution. I know it's something about it diluting the solution but can you please explain fully? Thx!

If you rinse the buret with water, some water will remain in the buret (unless you dry it thoroughly). The remaining water will dilute the titrant, making it's molarity less that what you think it is. So when you do your calculations you will be using a number for the titrant molarity that is too high
