:: a. Make sure the valve is closed

:: b. Put some of the chemical into a beaker

:: a. Make sure the valve is closed, and there is nothing underneath the buret

:: b. Put some of the chemical into a beaker

:: c. Pour the chemical in against the sides of the buret so it drips down and does not splatter

:: d. Now put the solution you will be adding to under the buret.

5. Reading the Buret

:: a. You need to record the initial volume in the buret. Look at the bottom of the meniscus to get an accurate measurement.

:: b. After you have let out all the chemical you need to for the experiment, record your final amount of solution in the buret.

:: c. Subtract the final measurement from the initial measurement to find out how much chemical you used

6. Cleaning Up

:: a. Pour the left over chemical (from the buret) back into the original container either through the tip (a little left) or the top (a lot left). Ask Mr. Mcleod where to dump the solution you created during hte experiment

:: b. Rinse the buret with DI water exactly as you did in the beginning. Repeat rinse several times
