№5.5 (с. 26)
Условие. №5.5 (с. 26)
скриншот условия
5.5 Изменятся ли свойства элемента Вольты, если его медный электрод заменить цинковым или цинковый заменить медным?
Решение. №5.5 (с. 26)
Решение
Да, в обоих случаях свойства элемента Вольты изменятся кардинально. Принцип действия любого гальванического элемента, включая элемент Вольты, основан на возникновении разности электрохимических потенциалов между двумя различными металлами (электродами), погруженными в электролит. Эта разность потенциалов создает электродвижущую силу (ЭДС), которая и является причиной возникновения электрического тока в замкнутой цепи.
Если его медный электрод заменить цинковым
В этом случае оба электрода в элементе будут цинковыми. Поскольку электроды изготовлены из одного и того же металла, разность потенциалов между ними будет равна нулю ($ЭДС = 0$). Без разности потенциалов элемент не сможет создавать электрический ток. Таким образом, он перестанет функционировать как источник питания.
Ответ: Да, свойства элемента изменятся — он перестанет быть источником электрического тока.
Если цинковый электрод заменить медным
В этом случае оба электрода окажутся медными. Как и в предыдущем сценарии, между двумя одинаковыми электродами разность потенциалов отсутствует ($ЭДС = 0$). Элемент Вольты потеряет свое основное свойство — способность генерировать электрический ток.
Ответ: Да, свойства элемента изменятся — он перестанет быть источником электрического тока.
