The most common sources of systematic error in a titration experiment are errors in calibration. The concentrations of substances used could be incorrect.
Random Error: errors that affect your precision in your experiment Systematic Error: errors that affect you accuracy in your experiment
how to reduce the problem of random error and systematic error while doing an experiment
parallax error - reading of volume of burette
You can overcome or reduce the problem of random error and systematic error while doing an experiment by increasing the sample size, which means averaging over a huge number of observations.
