Dissociation events in H_2 O H^ + +OH^ - is termed as ionization … - Vidyadip

MCQ

Dissociation events in $\mathrm{H}_2 \mathrm{O} \rightarrow \mathrm{H}^{+}+\mathrm{OH}^{-}$ is termed as ionization because:

✓
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

Correct option: 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.

$\mathrm{H}_2 \mathrm{O} \rightarrow \mathrm{H}^{+}+\mathrm{OH}^{-}$
This dissociation is termed as ionization because initially there is a polar covalent compound $\mathrm{H}_2 \mathrm{O}$.
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.
