Question

How many moles of electrons are required to electroplate a $0.5$ mole of silver from a nitrate solution?

• A. $0.5$
• B. $1$
• C. $27$
• D. $54$
• E. $108$

Answer 1

Answer: (A)

$0.5$

$A{g}^{+}+e^{-}\to Ag$
The electroplatingof 1 mole of silver from 1 mole of silver nitrate requires 1 mole of electrons.
The electroplatingof $0.5$ mole of silver from $0.5$ mole of silver nitrate will requires $0.5$ mole of electrons.
