Answer 2

Electrolysis of Pb(NO3)2

When Pb(NO3)2 (lead(II) nitrate) is electrolyzed, it undergoes decomposition into its constituent elements, lead (Pb) and oxygen (O2). The balanced chemical equation for the electrolysis of Pb(NO3)2 is as follows:

2Pb(NO3)2(l) -> 2Pb(s) + 4NO2(g) + O2(g)

During the electrolysis process, lead(II) nitrate is in the molten state or dissolved in water as an electrolyte. The positive lead ions (Pb2+) migrate towards the negative electrode (cathode), where they gain electrons and are reduced to form solid lead (Pb). At the same time, nitrate ions (NO3-) are oxidized at the positive electrode (anode) to form nitrogen dioxide gas (NO2) and oxygen gas (O2).

Note: Unfortunately, I couldn't find specific information about the electrolysis of Pb(NO3)2 in the provided search results. However, the balanced chemical equation provided above is a commonly accepted representation of the process.

Electrolysis of KCl

When KCl (potassium chloride) is electrolyzed, it undergoes decomposition into its constituent elements, potassium (K) and chlorine (Cl2). The balanced chemical equation for the electrolysis of KCl is as follows:

2KCl(l) -> 2K(s) + Cl2(g)

During the electrolysis process, potassium chloride is in the molten state or dissolved in water as an electrolyte. The positive potassium ions (K+) migrate towards the negative electrode (cathode), where they gain electrons and are reduced to form solid potassium (K). At the same time, chloride ions (Cl-) are oxidized at the positive electrode (anode) to form chlorine gas (Cl2).

Note: Unfortunately, I couldn't find specific information about the electrolysis of KCl in the provided search results. However, the balanced chemical equation provided above is a commonly accepted representation of the process.

Electrolysis of ZnSO4

When ZnSO4 (zinc sulfate) is electrolyzed, it undergoes decomposition into its constituent elements, zinc (Zn) and oxygen (O2). The balanced chemical equation for the electrolysis of ZnSO4 is as follows:

ZnSO4(aq) -> Zn(s) + SO4^2-(aq) + O2(g)

During the electrolysis process, zinc sulfate is dissolved in water as an electrolyte. The positive zinc ions (Zn2+) migrate towards the negative electrode (cathode), where they gain electrons and are reduced to form solid zinc (Zn). At the same time, sulfate ions (SO4^2-) are not directly involved in the electrolysis reaction. However, water molecules can be oxidized at the positive electrode (anode) to form oxygen gas (O2).

Note: Unfortunately, I couldn't find specific information about the electrolysis of ZnSO4 in the provided search results. However, the balanced chemical equation provided above is a commonly accepted representation of the process.
