aqueous solutions,I want you to tell me I)the ions present II) the ion discharged at each electrode 1) NaOH 2) PbBr2 3) CuSO4 4) HCl 5) KOH?

1) NaOH
I) There is Na⁺ ion from NaOH, H⁺ ion from water, and OH⁻ ion from both NaOH and water.
II) OH⁻ ion is discharged at the anode, and H⁺ ion is discharged at the cathode.

2) PbBr₂
I) There are Pb²⁺ and Br⁻ ions from PbBr₂, and H⁺ and OH⁻ ions from water.
II) Br⁻ ion is discharged at the anode, and Pb²⁺ ion is discharged at the cathode.

3) CuSO₄
I) There are Cu²⁺ and SO₄²⁻ ions from CuSO₄, and H⁺ and OH⁻ ions from water.
II) OH⁻ ion is discharged at the anode, and Cu²⁺ ion is discharged at the cathode.

4) HCl
I) There is Cl⁻ ion from HCl, OH⁻ ion from water, and H⁺ ion from both NaOH and water.
II) Cl⁻ ion is discharged at the anode, and H⁺²⁺ ion is discharged at the cathode.

5) KOH
I) There is K⁺ ion from KOH, H⁺ ion from water, and OH⁻ ion from both KOH and water.
II) OH⁻ ion is discharged at the anode, and H⁺ ion is discharged at the cathode.
