Why does LiCl does not exhibit frenkel defect?
tino4ka555 [31]
Frenkel defect is a defect in crystalline solids in which an atom is displaced from its lattice position to an interstitial space. This creates a vacant space at the original site and an  interstitial defect at the new site within the same element. This defect does not affect the chemical properties of the compound. This defect usually occur in ionic solids with large size difference between the anion and cation.
LiCl does not exhibit Frenkel defect because the size difference between the anion and the cation of the compound is very small.

How many moles of S2O8 2– react for every mole of S2O3 2– that reacts? Consider the balanced chemical equations for reactions 1
rewona [7]

For 1 mole of S₂O₃²⁻  0.5 mole of S₂O₈²⁻  will be used.

<h3>What is a balanced Reaction ?</h3>

A reaction in which the number of atoms in reactants is equal to the number of atoms in the products is called a balanced reaction.

The reaction given in the question is

S₂O₈²⁻   + 2I⁻      ⇄   2SO₄²⁻ + I₂

I₂ + 2S₂O₃²⁻ ⇄ 2I⁻ + S₄O₆²⁻

Adding the equation will give balance equation

S₂O₈²⁻  + 2I⁻  + 2S₂O₃²⁻   ⇄ 2SO₄²⁻  + 2I⁻ + S₄O₆²⁻

So x moles of S₂O₈²⁻ require 2x of S₂O₃²⁻

for 1 mole of S₂O₃²⁻  0.5 mole of S₂O₈²⁻  will be used.
