S2O82–(aq) + 2I–(aq) 2SO42–(aq) + I2(aq) The reaction can be carried out in the presence of a fixed amount of aqueous thiosulfate ions, S2O32–(aq), which reduces the iodine back to iodide. 2S2O32–(aq) + I2(aq) …
WebFiltering under reduced pressure. Attaching the apparatus to a running tap (or a hand-pump) pulls air out of the flask, which pulls liquid through the funnel. This is much faster than simple filtration and helps dry the crystals a little by sucking air through them. A Buchner funnel is generally used and filter paper is used to cover the holes.
