Question

Which of the following statements is not an advantage of the galvanic series over the EMF series? Question 9 options: a) The galvanic series does not predict voltages between dissimilar metals in contact with an electrolye. b) The galvanic series include engineering aloys as well as pure metallic elements. c) The electrolye for the galvanic series is common seawater rather than solutions with precise concentrations of metallic ions. d) None of the other options shown.

Answer 1

Gavanic series is decides the nobility of metal and semi metals and dissimilar metals by representing electrical potential between them, which clearly indiacate that less noble metal is which having lower or negative potential difference and acts as anode. In galvanic series anode corrode more fastly than cathode. b) sentence is also correct that gavanic series can use for metals, semi metals and dissimilar metals. General study of galvanic series is done with low oxygen content means stagnant seawater. So answer is option (a).
