... Point defects: When ions or atoms do not hold the theoretical position, this is called point defect. Point defects are of two types: Stoichiometric defects: Schottky defect: Due to missing of ions from lattice point in pairs. Frenkel defect: It is caused due to the creation of lattice vacancy as a r ...

In the reduction part from chromate (Cr: +7) to Cr3+ (+3) we balance the oxygen by adding 8 H+ on the left to form 4 H2O on the right: CrO42- + 8H+ Cr3+ + 4H2O Now the charge on the left is 6+, that on the right is only 3+, so to balance the charge we add 3 electrons to the left: CrO42- + 8H+ + 3e ...
