Question
Write the balanced symbol equation for the electrolysis of molten lead(II) bromide (PbBr2).
Answer
The balanced symbol equation for the electrolysis of molten lead(II) bromide is: PbBr2 (l) → Pb (l) + Br2 (g).
Explanation
This question tests the student's ability to apply knowledge of electrolysis to write balanced equations. It requires understanding of the products formed at the electrodes during the electrolysis of a specific ionic compound.
Common mistake
Common Mistake in Writing Balanced Equations
Students often forget to balance the number of atoms of each element on both sides of the equation when writing balanced symbol equations for electrolysis.
To fix this, carefully count the number of atoms of each element in the reactants and products, and adjust the coefficients to ensure they are equal on both sides.
