Compounds that can conduct electricity are called electrolytes.
Electrolysis occurs when an electric current decomposes an ionic compound in solid state.
The anode is the negative electrode.
In an electrolysis setup, the bulb will light if the solution in the beaker is an electrolyte.
Negative ions move to the anode during electrolysis.
The cathode is the positive terminal connected to the power supply.
During electrolysis, positive ions move to the anode.
Lead(II) bromide is ionically bonded and contains Pb²⁺ and Br⁻ ions.
During the electrolysis of molten lead(II) bromide, lead ions move to the anode.
The product at the anode in the electrolysis of molten lead(II) bromide is lead metal.
The reaction at the cathode during the electrolysis of lead(II) bromide is Pb²⁺(l) + 2e⁻ → Pb(l).
The reaction at the anode during the electrolysis of lead(II) bromide is 2Br⁻(l) → Br₂(g) + 2e⁻.
Hydrogen gas forms at the anode when dilute sulfuric acid is electrolysed.
The reaction at the cathode during the electrolysis of dilute sulfuric acid is 2H⁺(aq) + 2e⁻ → H₂(g).
When concentrated sodium chloride solution is electrolysed, chlorine gas is observed at the cathode.
