Witryna18 mar 2024 · When NaCl is doped with SrCl 2, it leads to an impurity defect. Impurity defect is defined as a defect which arises when a foreign atom replaces a host atom at the lattice site. The process of adding impurities to the crystal is known as doping. In the given case, to maintain electrical neutrality, each Sr 2+ ion replaces two Na + ions. ts3 gamersclub
