Question

При алюмирывании детали в течение 2 ч сила тока, проходящего через ванну, была 30 А. Электрохимический эквивалент никеля к = 3 • 107 кг/Кл. Вычислите массу алюминия?​

Answer 1

Ответ:

Объяснение:

Дано:

t = 2 ч = 7200 c

I = 30 А

k = 3·10⁻⁷ кг/Кл

_____________

m - ?

m = k·I·t

m = 3·10⁻⁷·30·7200 ≈ 65·10⁻³ кг   или  m = 65 г

Answer 2

Calculation of Aluminum Mass during Electroplating

To calculate the mass of aluminum deposited during the electroplating process, we can use Faraday's law of electrolysis, which states that the mass of a substance produced at an electrode during electrolysis is directly proportional to the quantity of electricity passed through the cell.

Given: - Time (t) = 2 hours = 7200 seconds - Current (I) = 30 A - Electrochemical equivalent of nickel (E) = 3 * 10^7 kg/C

Solution:

Using Faraday's law of electrolysis: Mass (m) = E * I * t

Substitute the given values: m = 3 * 10^7 kg/C * 30 A * 7200 s

Calculating the mass: m = 6.48 * 10^12 kg

Therefore, the mass of aluminum deposited during the electroplating process is 6.48 * 10^12 kg.
