Sample Questions
Which of the following are functions of a salt bridge in a galvanic cell?
Show answer
Maintains electrical neutrality, Prevents mixing of solutions, Completes the internal circuit

In the electrolysis of water, hydrogen gas is produced at the cathode.
Show answer
True
During electrolysis of water, hydrogen gas is produced at the cathode through reduction: 2H₂O + 2e⁻ → H₂ + 2OH⁻
Which of the following metals can displace hydrogen from dilute acids?
Show answer
Magnesium, Zinc, Iron
Metals above hydrogen in the reactivity series (like Mg, Zn, Fe) can displace hydrogen from dilute acids. Copper and silver are below hydrogen.
Primary cells can be recharged and used again.
