What are the ions present in NaCl?
Two ions of Na and one ion of Cl
Na ions only
One ion of Na and one ion of Cl
Cl ions only
The ions present in NaCl is one ion of Na and one ion of Cl.
If NaCl is doped with 10−3mol % of SrCl2′, each Sr2+ ion replaces two Na+ ions, but occupies only one lattice point in place of Na+ ion. This creates one cation vacancy.
