Question

Во время электролиза на катоде выделилось 25 г серебра. Сколько времени длился электролиз, если сила тока была 0,5 А, а электрохимический эквивалент серебра равен 1,12 мг / Кл? 25 с 0,5 с 44643 с 25000 с Помогите пожалуйста!!!Срочноооо​

Answer 1

Ответ:

44643c

Объяснение:

∆t=m/k/I=0,025/1,12*10^(-6)/0,5=44643c

Answer 2

Calculation of Electrolysis Duration

To calculate the duration of the electrolysis process, we can use the formula:

Time (s) = Amount of Substance (g) / (Current (A) * Electrochemical Equivalent (mg/Coulomb)).

Given: - Amount of silver deposited on the cathode: 25 g - Current: 0.5 A - Electrochemical equivalent of silver: 1.12 mg/Coulomb

Substituting these values into the formula, we can calculate the duration of the electrolysis:

Time (s) = 25 g / (0.5 A * 1.12 mg/Coulomb)

To simplify the calculation, we need to convert the units of the electrochemical equivalent from mg/Coulomb to g/Coulomb:

1.12 mg/Coulomb = 0.00112 g/Coulomb

Now we can substitute the values and calculate the time:

Time (s) = 25 g / (0.5 A * 0.00112 g/Coulomb)

Simplifying further:

Time (s) = 25 g / (0.00056 g/Coulomb)

Time (s) = 44643 s

Therefore, the duration of the electrolysis process was approximately 44643 seconds.

Please note that the calculation assumes ideal conditions and does not take into account any potential losses or inefficiencies in the electrolysis process.
