Question

Write the dissociation equation of AlCl₃ in water.

a) AlCl₃ = Al³⁺ + 3Cl⁻
b) AlCl₃ + 3H₂O = Al(OH)₃ + 3H⁺ + 3Cl⁻
c) AlCl₃ = Al²⁺ + 2Cl⁻
d) AlCl₃ + H₂O = Al(OH)₄⁻ + H⁺

Answer 1

The dissociation equation of AlCl₃ in water is AlCl₃ + 3H₂O → Al(OH)₃ + 3H⁺ + 3Cl⁻.

Step-by-step explanation:

The dissociation equation of AlCl₃ in water is:

AlCl₃ + 3H₂O → Al(OH)₃ + 3H⁺ + 3Cl⁻

When AlCl₃ is dissolved in water, it dissociates into Al³⁺ ions, H⁺ ions, and Cl⁻ ions. This is because the water molecules surround the AlCl₃ and separate the ions from each other.
