If the activity of halogens is stated as:Fluorine > Chlorine > Bromine > Iodine, determine if a reaction occurs and if so provide the products formed.
Cl2 (g) + AlBr3 (aq) →
A
3 Cl2 (g) + 2 AlBr3 (aq) → 2 AlCl3 (aq) + 2 Br2 (l)
B
3 Cl2 (g) + 2 AlBr3 (aq) → 2 AlCl3 (aq) + 3 Br2 (l)
C
3 Cl2 (g) + AlBr3 (aq) → AlCl3 (aq) + 3 Br2 (l)
D
No reaction
Verified step by step guidance1
Identify the reactants and products in the given chemical equation: Cl2 (g) + AlBr3 (aq).
Understand the activity series of halogens: Fluorine > Chlorine > Bromine > Iodine. This indicates that a more active halogen can displace a less active halogen from its compound.
Determine if a reaction occurs by comparing the activity of chlorine and bromine. Since chlorine is more active than bromine, it can displace bromine from AlBr3.
Write the balanced chemical equation for the reaction: 3 Cl2 (g) + 2 AlBr3 (aq) → 2 AlCl3 (aq) + 3 Br2 (l).
Verify the stoichiometry of the balanced equation by ensuring that the number of atoms of each element is equal on both sides of the equation.
