Question

На электроде в электрической ванне за 10 минут при силе тока 6А выделилось 1,224 г цинка. Определите электрохимический эквивалент цинка. ПОЖАЛУЙСТА ОЧЕНЬ СРОЧНО.

Answer 1

M=k*I*t
k=m/I*t=1,224*10^-3/6*600=0,34*10^-6 кг/Кл

Answer 2

Calculation of the Electrochemical Equivalent of Zinc

To determine the electrochemical equivalent of zinc, we can use the formula:

Electrochemical Equivalent = Mass of Substance Deposited / Charge Passed

In this case, we are given that in an electric bath, 1.224 grams of zinc were deposited in 10 minutes with a current of 6A.

Using the formula, we can calculate the electrochemical equivalent of zinc as follows:

Electrochemical Equivalent = 1.224 grams / (6A * 10 minutes)

Let's calculate the value:

Electrochemical Equivalent = 1.224 grams / (6A * 10 minutes) = 0.0204 grams per coulomb

Therefore, the electrochemical equivalent of zinc is 0.0204 grams per coulomb.

Please note that the calculation assumes that the deposition of zinc is the result of the reduction of Zn2+ ions in the solution. The actual value may vary depending on the specific conditions of the experiment.

I hope this helps! Let me know if you have any further questions.
