The same current was passed successively...

The same current was passed successively through the solutions of zinc sulfate and nickel ammonium sulfate (rendered alkaline with ammonia). The weights of zinc and nickel deposited in a certain time were found to be 0.531 and 0.477 g. respectively. Given that the equivalent weight of zinc is 32.7, calculate that of nickel.

Text Solution

AI Generated Solution

To solve the problem, we will use the relationship between the weights of the metals deposited and their equivalent weights. The formula we will use is: \[ \frac{M_z}{M_n} = \frac{E_z}{E_n} \] where: - \(M_z\) = weight of zinc deposited ...
