Question

An ion is reduced to the element when it absorbs $6\times 10^{20}$ electrons. The number of equivalents of the ion is:

• A. $0.1$
• B. $0.01$
• C. $0.001$
• D. $0.0001$

Answer 1

Answer: (C)

$6\times 10^{23}$ electrons = 1 equivalent
$\therefore 6\times 10^{20}$ electrons $=\frac{6\times 10^{20}}{6\times 10^{23}}=0.001$ equivalent
