Possible methods that would improve the experiment accuracy would be to perform the experiment with one person allocated to open and close the tap of the burette while also reading the colour change this would allow that experimenter to know when exactly to stop the tap when the solution has shown a colour change. Ensuring that the person who is reading the meniscus value after each titration knows exactly that the bottom of the meniscus is the values that must be recorded, this would eliminate the possibility of incorrect values. Measuring the volume of each substance should be done with care and precision to ensure that the experiment results in accurate values. A burette leak in most cases unidentifiable because it may leak at such a small scale that it isn’t noticeable. This can be minimised by ensuring the burette is tightly closed and closely monitoring the volume of the substance contained inside the burette.
