Do not count mispronunciations of difficult proper nouns in the oral reading pas-. sages as errors. You may pronounce these for the children if necessary. Also, do not. count as errors dialectical equivalents (nonstandard dialects); however, these should. be noted.
A galvanic cell is also called a voltaic cell. The spontaneous reactions in it provide the electric energy or current. Two half cells can be put together to form an electrolytic cell, which is used for electrolysis. In this case, electric energy is used to force nonsponaneous chemical reactions.
Electrolytic vs Galvanic Cells. Electrolytic and galvanic cells are two types of electrochemical cells. In both electrolytic and galvanic cells, oxidation-reduction reactions are taking place. In a cell, there are two electrodes called an anode and a cathode. Oxidation reaction takes place on the anode, and the reduction reaction takes place on the cathode. Electrodes are immersed in separate electrolyte solutions.
