For 10 points each, answer the following about the work of Czech scientists in electrochemistry.
[10m] Czech scientist Jaroslav Heyrovský invented polarography, which is a form of voltammetry that uses a dropping electrode of this element. Three atoms of this metal can form into a triangular ion with a +4 charge.
ANSWER: mercury [or Hg]
[10h] This equation, partly named for a Czech scientist, states that the peak current of a cyclic voltammetry experiment is proportional to the square root of the product of scan rate, the Faraday constant, and the diffusion coefficient.
ANSWER: Randles–Ševčík equation
[10e] Heyrovský’s polarography setup has a larger voltage window than standard hydrogen electrodes, whose reduction potential equals this many volts. This is the redox potential between two identical electrodes.
ANSWER: zero volts [or 0]
