Ah sorry, I should've clarified it better. I weighed out the 0.2416 g disodium EDTA and put it in the 250 mL volumetric flask so I could dilute it to the mark. After I did that, I poured the solution into a plastic bottle because its safer that way. (No metal ions in plastic bottle). So in my...
I prepped it with 250 mL. I put the disodium EDTA in a 250 mL volumetric flask and diluted it to the mark, so I assume it's that. We used water from the faucet in our lab.
I weighed out 0.2416 g disodium EDTA and diluted it with about 250 mL of H2O and stuck it in a plastic bottle to use for titration. My question is, to determine the molarity of my stock EDTA standard sol'n, is it just (0.2416g / 292.25 g) / 0.250 L = 0.00331 M? Or do I have to use the VOLUME of...
