Question

A 100.0mL dilute solution of Ag⁺ is electrolysed for 15.0 minutes with a current of 1.25mA and the silver is removed completely. What was the initial [Ag⁺]?

• A. \(2.32\times10^{-1}\)
• B. \(2.32\times10^{-4}\)
• C. \(2.32\times10^{-5}\)
• D. 1.16×10⁻5

Hint:

In electrolysis, moles of ions discharged are obtained directly from charge passed.
