Web13 apr. 2024 · FE-SEM and TEM micrographs indicate that the presence of Sr in the lattice of Cr 2 O 3 increased the roughness of resulting NSs attributed to high surface area and high surface energy. Sr doping enhances the surface area of NPs, leading to a more significant formation of reactive oxygen species and, ultimately, a higher antibacterial effect. WebStrontium chloride has the chemical formula SrCl2. When strontium chloride dissociates, or separates, into its ions in water, strontium two plus ions and chloride one minus ions go into solution. In other words, they dissolve. We say soluble salts dissociate into ions. Since it is an aqueous solution, water is the solvent.
