Question

Which is an example of ionization?

Answer 1

Answer:  $Mg(OH)_2\rightarrow  Mg^{2+}+2OH^–$

Explanation:

Ionization is a type of chemical reaction in which one reactant gives ions on decomposition.

$A\rightarrow B^++C^-$

1. $C+O_2\rightarrow CO_2$ is an example of is an example of synthesis reaction in which two reactants are combining to form one product.

2. $H_2CO_3\rightarrow H_2O+CO_2$ is an example decomposition is a type of chemical reaction in which one reactant gives two or more than two products.

3. $SO_2+H_2O\rightarrow HSO_3^-+H^+$ : is an example of synthesis reaction in which two reactants are combining to form one product which being a strong electrolyte dissociate into ions.

4.  $Mg(OH)_2\rightarrow  Mg^{2+}+2OH^–$ is an example of ionization in which one reactant gives ions on decomposition.

Answer 2

Ionization is a formation of ions from neutral atoms or molecules.

SO₂ + H₂O = HSO₃⁻ + H⁺

Mg(OH)₂ = Mg²⁺ + 2OH⁻
