net ionic equation for ASCl3 + 3 H2O = 3 HCl + AS(OH)3?

AsCl₃ is a molecular compound. Hence, it is written in molecular form.
H₂O is a molecular compound. Hence, it is written in molecular form.
HCl is a strong acid which completely dissociates in water. Hence, it is written in ionic form, i.e. H⁺ and Cl⁻
As(OH)₃ in a weak acid with pKₐ = 9.2, and most of As(OH)₃ in aqueous solution exists as molecules. Hence, it is written in molecular form.

Therefore, the net ionic equation is :
AsCl₃(l) + 3H₂O(l) → 3H⁺(aq) + 3Cl⁻(aq) + As(OH)₃(aq)

Balanced equation:
ASCl3 + 3 H2O = 3 HCl + AS(OH)3
Reaction type: double replacement

Too advance for me
