Quizplus · Accepted Answer

Ignition is a process of heating a precipitate at a high temperature to convert it to a known and constant composition. This is done by burning off any impurities or volatile substances that may have contaminated the precipitate during the experiment. Ashless filter paper (A), a fritted-glass funnel (B), a rubber policeman (D), and a dessicator (E) are not used for the purpose of converting a precipitate to a known, constant composition.
