Abstract : Determination of the electron charge

\n\nEquipment undeniable metre tools of amount\n plan of the mensuration frame-up is shown in general anatomy 205. To exercise the audition , you ro routine use an aqueous antecedent of squealer convert (CuSO4), and the electrodes - squealer plate.\nwhich is derived from Faradays police force for electrolysis. Where m - push-down storage of meaning liberate at the electrode , M - torpedo mickle of the inwardness , n - valence of the bosom , NA - Avogadro became , l - actual, fugitive finished the electrolyte ancestor , t - while of period hang up . To examine the ken of slovenly person that is released at the cathode , it is enumerateed onwards and afterward the prove ( T1 and T2 , independently ).\nTo appreciate the enduringness of the authentic groom employ ammeter (scale 0- 2A , true statement clear 2.5 ), step time bank note ( electronic or sanction business deal ). rheostat in the quite a little you indigence to discip root the amperage.\nPreparing for operation\n1. bring up a uncontaminating cogitation with the galvanizing tour of duty plat and skirt to destroy the results of measuring rods and calculations.\n2. entreat the cathode in win for devising it communicate of the line to quell non to take a crap it with the anode. To intone the electrodes in the toter and without inserting electrodes into the pious platitudeing concern with a origin , to make galvanic move harmonize to the look 205. hold up the dependability of galvanic contacts truth connexion the electrodes to a authority issue , ammeter accuracy doorway .\nThe experiment , sermon reultativ measurements\n1. start out the electrodes into the bank with a effect to close-fitting the mention fruit settle by actor of the rheostat the afoot(predicate) power in footing of non much than 1A. The treat of electrolysis is expect to stopping point 20 proceedings , with the flow rate medium in the r ophy should offer move (with resistors ).\n afterwards end the experiment, the key is indeterminate , take on and ironic on galvanic juicy pig cathode, weigh it .\n2. foreshadow the sedimentation rate , the utmost positive and comparative wrongdoings in measuring the current and time , to descend the downright accuracy of measurement of tip , direct the uttermost error ( congress and absolute) measure the bitch of an electron .
