Prepare the buret.

Place an empty waste beaker beneath the buret.

Open the stopcock and rinse the buret with $5-10$ mL of deionized water.

Next, rinse the buret at least two times with $5-10mL$ of NaOH solution, collecting the waste in the beaker. $($This step insures the buret is coated in the solution to be titrated.$)$

Close the stopcock.

Fill the buret to just past $0mL$ with NaOH solution.

Open the stopcock to release enough NaOH so the buret volume reads between $0-3$ mL$.$

The collected waste solutions in the beaker may be poured down the drain.

Place the Erlenmeyer flask below the buret to begin titration.

Record the initial volume of NaOH below.
