WebHow is the standard reduction potential of a half-cell determined? by direct measurement of the potential with a voltmeter; by measuring the voltage of a cell with a standard hydrogen electrode; by measuring the voltage of a cell with a standard mercury electrode; by connecting two of the half-cells in opposite directions and measuring the voltage
WebIn reduction you want to opposite to happen, a gain in electrons, so a strong force of attraction on your valency electrons is needed. Li has the smallest radius (and all of group one has the same nuclear charge) so Li has the strongest force of attraction and thus most easily atracts more electrons. ( 3 votes) Show more...
