Answer:
The answer to your question is below
Explanation:
Polyatomic ions are ions composed for more than 1 atom. There are polyanions and polycations.
Polyanions have a negative charge and polycations have a positive charge.
Examples
Polyanions Polycations
acetate CH₃COO⁻ ammonium NH₄⁺¹
bromate BrO₃⁻
chlorate ClO₃⁻
hydroxide OH⁻
nitrate NO₃⁻
nitrite NO₂⁻
sulfate SO₄⁻²
phosphate PO₄⁻³
permanganate MnO₄⁻
We write parentheses before or after a polyatomic ion to emphasize that the oxidation number of the atom which interacts with it affects all the atoms that form part of the polyatomic ion.
Answer:
You need to have a clean surface for contact between the solution and the material.
Explanation:
The presence of impurity on the surface of the material, and lack of surface uniformity (smoothness) can reduce the effective contact between material and solution and can interfere with the electroplating process's success.
