Summary
| Description |
English: Electrochemical element - a battery
Zinc and copper rods, in a solution of electrolyte (table salt, lemon juice) show a potential difference, due to dissolving the less noble metal. Upon dissolving, the metal (zinc) cations end in the solution, while the electrons travel through the conductor (LEDs in our case), from the zinc (–), to the copper (+): Zn(s) → Zn2+(aq) + 2e– (reaction of the negative electrode) 2е– + 2Н+(aq) = H2(g) (reaction of the positive electrode, Cu) Performed by the retired Prof. PhD Vladimir Petruševski. The planning of the experiment also included the Prof. PhD Miha Bukleski and the students Mihail Trajkov and Darko Stojčev, Department of Chemistry, FNSM, Ss. Cyril and Methodius University, Skopje, Macedonia.Македонски: Eлектрохемиски елемент - батерија
Шипки од цинк и од бакар, ставени во раствор од електролит (раствор од готварска сол, сок од лимон), покажуваат разлика во потенцијалите, која се должи на растворање на помалку благородниот метал. При растворањето, катјоните од металот (цинкот) одат во раствор, а доколку струјното коло е затворено, електроните патуваат преку спроводникот (светлечки диоди), од цинкот (–) кон бакарот (+): Zn(s) → Zn2+(aq) + 2e– (реакција на негативната електрода) 2е– + 2Н+(aq) = H2(g) (реакција на позитивната електрода, Cu) Изведено од пензионираниот Проф. д-р Владимир Петрушевски. Во планирањето на опитот, исто така беа вклучени Проф. д-р Миха Буклески, и студентите Михаил Трајков и Дарко Стојчев, Институт за хемија, ПМФ, УКИМ, Скопје, Македонија. |
