Sodium chloride pH Presence of disaccarides
You might measure wrong the second time
The presence of bubbles affect the correct volume of the titrant.
Sources of error are inevitable in a lab scenario no matter how careful you are. Contamination, limitations of measurement, and human error are the most often-encountered errors. A theoretical yield represents the perfect world of math (stoichiometry.)

parallax error - reading of volume of burette
The main sources of error in a solubility curve are based on the formation of crystals. The position of the thermometer in the beaker may be another source of error.
Since pKa values are estimations, they can have sources of error. Some possible sources include incorrect measurements of non-aqueous solvents, which is needed for the estimation, or an error in calculating the equation..
A compounded error is an error caused by something which is unforeseen, such as extreme weather conditions.

What are some precautions and source of error in the principle of moments
The most common sources of systematic error in a titration experiment are errors in calibration. The concentrations of substances used could be incorrect.
Survey error is the extent to which findings from the survey sample differ from those of the population of interest. The large nationally representative surveys discussed here are designed to minimize error. Nevertheless, it is impossible to eliminate all of the multiple potential sources of error. Investigators must identify and consider how potential survey error can bias the results of their analyses. Statistical strategies can minimize the impact of these potential sources of error on study findings.
