Describe the standard hydrogen electrode assigned 0 V and the conditions for measuring a standard electrode potential, and interpret E° values from the data booklet: a more positive value means a stronger oxidizing agent that is more easily reduced.
The cyanide ion acts as a ligand in many complex ions, for example hexacyanoferrate(III), . (i) State the type of bond, as precisely as possible, that joins each cyanide ion to the iron ion. (ii) Deduce the oxidation state of iron in…
During discharge, sodium atoms stored in the hard carbon are converted into sodium ions. (i) State the half-equation for the process taking place at the anode while the battery discharges. (ii) With reference to section 19 of the data booklet, comment on the…
