Zinc loses electrons more readily than copper. Zinc cations are less likely to accept electrons than copper cations. This makes zinc a stronger ____________ than copper.
The electrochemical series is valid for which conditions?
In galvanic cells, the stronger reductant is the half cell with the positive/negative electrode?
In galvanic cells, the stronger oxidant is the half cell with the positive/negative electrode?
The higher of the two half cell reactions in the electrochemical series goes forward/backward.
The lower of the two half cell reactions in the electrochemical series goes forward/backward.
Oxidation involves the loss/gain of electrons
Reduction involves the loss/gain of electrons
True or false?
The movement of ions from the salt bridge into the half cell maintains electrical neutrality.
In a galvanic cell the stronger oxidant will be oxidised/reduced and the stronger reductant will be oxidised/reduced.
A current flows in a galvanic cell because one half cell has a greater tendency to push electrons into the external circuit than the other half cell. This is called the ...
