Ana Sofi´a Varela; Alfonso Garci´a-Ma´rquez – Journal of Chemical Education, 2023
This laboratory experiment consists of the synthesis of two series of alkaline-earth titanates (calcium-strontium and strontium-barium)to corroborate Vegard's law by obtaining their X-ray diffraction patterns and plotting the lattice parameter versus mole fraction of both cations. This experiment allows students to understand the key concepts in…
