Explain whether each of the following is a source of experimental error: a) A student obtains three Erlenmeyer flasks, and he washes and rinses them. He dries the outside of each flask, but not the inside. He then weighs out his KHP for each trial, and transfers the KHP to the appropriate flasks. b) He does not condition the buret. c. He does not fill the buret tip with solution before the first titration.
