Question
A solution containing $\mathrm{Pt}^{4+}$ is electrolyzed with a current of $4.00 \mathrm{~A}$. How long will it take to plate out $99 \%$ of the platinum in $0.50 \mathrm{~L}$ of a $0.010 \mathrm{M}$ solution of $\mathrm{Pt}^{4+}$ ?
Step 1
First, we need to determine the amount of platinum in the solution. We can do this by multiplying the volume of the solution by its concentration: Amount of Pt = Volume × Concentration Amount of Pt = 0.50 L × 0.010 mol/L = 0.005 mol Show more…
