statement 1: priming the mohr pipette helps to remove possible contamination resulting from chemicals previously used in the pipette.

select one:

only statement 2 is true
both statements are true
both statements are false

Explanation:

Statement 1 is true as priming a Mohr pipette helps remove residual chemicals and contaminants. Statement 2 is false because when using a Mohr pipette, one must pay attention to both the starting and final graduation lines for accurate volume - dispensing, regardless of starting at 0.00 mL.

Only statement 1 is true
