…The order of ionization tendency of the major elements when the solvent is water is K>Ca>Na>Mg>Al>Zn>Cr>Fe>Cd>Co>Ni>Sn>Pb>(H)>Cu>Hg>Ag>Pt>Au. This order is called the ionization series or electrochemical series. When a metal with a higher ionization tendency than hydrogen is placed in a dilute aqueous solution of acid, the metal spontaneously dissolves and hydrogen gas is generated. … *Some of the terminology that refers to the "ionization series" is listed below.

…溶媒が水のときの主要な元素のイオン化傾向の順は, K>Ca>Na>Mg>Al>Zn>Cr>Fe>Cd>Co>Ni>Sn>Pb>(H)>Cu>Hg>Ag>Pt>Auである。このような序列をイオン化列ionization seriesまたは電気化学列electrochemical seriesという。水素よりもイオン化傾向の大きい金属を酸の希薄水溶液中に入れると,その金属は自発的に溶けて水素ガスが発生する。… ※「ionization series」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
