Question
The same current was passed successively through solution of zinc−ammonium sulphate and nickel−ammonium sulphate rendered alkaline with ammonia. The weights of zinc and nickel deposited in a certain time were found to be 22.89 g and 20.55 g, respectively. Given that the chemical equivalent weight of zinc is 32.7, what is the chemical equivalent weight of nickel?
Options
A.58.71
B.29.36
C.14.39
D.36.42
Solution
$n_{eq}Zn = n_{eq}Ni \Rightarrow \frac{22.89}{32.7} = \frac{20.55}{E_{Ni}}$
$\therefore E_{Ni} = 29.36$
