Dilution of NaOH solution The NaOH solution provided is too concentrated and you will need to dilute it by a factor of 10. Make sure to show all the steps in your procedure. From your stockroom you need to select the 1M NaOH solution (1M is only estimated and is not accurate), distilled water, 25ml Pipette, and 250ml Volumetric Flask. With your pipette withdraw 25ml of the 1M NaOH solution and pour it into the volumetric flask. Take the distilled water and add the amount needed to fill the volumetric flask to 250ml. In case you run out of solution you can also duplicate your solution and create a new batch with the same properties, just right click on your mouse and duplicate. Remove all items except keep the volumetric flask with your diluted NaOH solution.
