MCQ
Dissociation events in H2​O → H+ + OH− is termed as ionization because:
  • A
    The electron is initially shared between both atoms, thus the dissociation event into ions involves the transfer of an electron from one atom to the other.
  • B
    It does not involve any electron transfer.
  • C
    Charged species formed.
  • D
    No charge species formed.

Answer

  1. The electron is initially shared between both atoms, thus the dissociation event into ions involves the transfer of an electron from one atom to the other.

Explanation:

H2​O ⟶ H+ + OH−

This dissociation is termed as ionization because initially there is a polar covalent compound H2​O.

This dissociation leads to the formation of ions H+ and OH−

This dissociation involves a transfer of an electron from one atom to another leading to the formation of charged species.
