Question

When does water affect the amount of H ions?

A) When frozen
B) When heated
C) When exposed to air
D) When undergoing electrolysis

Answer 1

Water affects the amount of H ions during electrolysis when an electrolyte is present.

Step-by-step explanation:

Water affects the amount of H ions during electrolysis. When direct current electricity passes through water containing an electrolyte, such as H₂SO4, bubbles of hydrogen form at the cathode. This is because the water molecules dissociate into H+ and OH- ions, and the H+ ions are reduced at the cathode to form hydrogen gas.
