Clamp the burette in a ring stand with the flask placed right below it. The bottom tip of the burette should come close to the top of the flask

Add 50 mL of the analyte to the flask. (Unknown concentration of HCl)

Add 50 mL of the titrant to the burette. (1 M NaOH)

Add three drops of an indicator. (Phenolphthalein)

Slightly open the valve of the burette, allowing the titrant to drip into the flask drop by drop.

Swirl the flask as the drops are added.

Once the drops start to turn pink for a prolonged period of time before turning back to clear while swirling, slow down the rate at which you add drops.

Add one drop at a time, then swirl until it fully turns back to clear before adding another drop.

Once it stays a pale pink color, that is your endpoint!

Measure the level of the burette to determine the volume of titrant added.
