Titration is a common method of analysis used in chemistry. It allows a chemist or student to determine the exact quantity of reactant by pinpointing the end of a reaction.

In order to perform a titration, follow these steps:

1. Prepare the buret by filling with titrant solution and checking for any leaks or air bubbles.

2. Record the initial volume reading and calculate the anticipated endpoint volume.

3. Place the sample to be analyzed in a sterile beaker/flask making sure that it is totally dissolved if it is a solid. Stir and add indicator.

4. Using the buret, add titrant to almost where you calculated your endpoint. Slowly proceed while examining the beaker color. To ensure all titrant is washed into the beaker or flask, rinse the sides and tip of the buret with a wash bottle. You should be able to recognize the endpoint. For instance, pheolphthalein's endpoint is very pale pink.

5. Record the final volume in the buret.

6. Now simply subtract the beginning volume to determine the amount of titrant used. To calculate the number of moles of reactant in your solution, use the concentration and amount of titrant plus the stoichiometry of the titration reaction.
