Obtaining reliable data by a titration:
To improve reliability:
_We conducted titration for 3 times which the results only differ by 0.1 moles or consistence through out the experiment
_We used controls such as:
_The same the amount of indicator used
_The volume of each concentration used each time

Choosing appropriate equipment and indicators
Choosing indicators
In the titration of Ethanoic acid against NaOH, the salt we receive is basic salt so the pH will be above 7. Therefore the indicator used will be phenolohthalein because it changes color from red to colorless

Choosing appropriate equipments:
Pipette is used to transfer the exact and accurate volume to the conical flask. In our case exactly 25ml of NaOH is delivered to conical flask.
Pipette increases the accuracy of the experiment because it is thin and has only one mark of exact volume.

Burette is used to measure the volume of acid needed for titration to reach the end point. It has a mark of zero at the top and an interval of 0.1ml. The tiny gap between each interval makes it easy for us to read the exact volume needed to reach the end point.

Retort stand is used to keep the burette in place so we don’t have to hold it so we can use our hands to control the tap and stir the conical flask

Conical flask is used for minimizing splashes out of the conical flask and also easier to swirl than beaker since it has small open at the top
