The bubble in the tip of the buret is not removed prior to performing the NaOH standardization. Will the reported concentration of the NaOH be greater than, less than, or equal to the true concentration of the NaOH if the bubble is flushed from the buret during the titration?

Question

I think the concentration would be greater than, but I am not sure if that is correct. I know the calculated volume will be different. But will it actually change the concentration?

Answer 1

Of course. It will change the calculated volume and since you are measuring the volume of the titrant + the volume of the bubble, it will be larger.
Since this is a molarity of the base, you will calculate M = mols/L
The indicator will change when mols acid you're titrating is the same as mole NaOH added but volume NaOH is greater which makes the M.......?
