Hi, what are the other evaluation/analysis points for a titration experiment? For example, using a white tile to see the colour change in the conical flask.

I’m not sure exactly what you mean by “evaluation/analysis” points.
Here are some of the things which you should do during a titration:
1 Clean the burette before use with pure water, and then again with some of the solution which is going to be used inside it later.
2 Ensure that there are no air bubbles in the jet of the burette by turning on the tap fully to expel all air from the burette. Then the tap can be turned on slightly so as to level the solution inside with the zero mark.
3 Clean the pipette with pure water and then with some of the solution which is going to be measured out with its use.
4 Use only a few drops of indicator.
5 Read the titre with the eye at the same level as the reading to be taken.
6 Carry out several titrations and use the median or modal value for the titre, not the mean.
Risk assessment
Before attempting any practical work based on the advice and suggestions on this website, you must do the following. Identify any hazards, assess the risks from these hazards, and then decide appropriate control measures to reduce the risks. You must have these approved by those in authority in your school or college laboratory. Do not rely on what is said on this website.
For further guidance see our tutorial on Risk Assessment.
