Abstract: The effect of V concn., acidity, and temp. of the soln. on compn. of the products of the reactions involving binary replacement in the systems NaVO₃-AcOH-Cd(OAc)₂-H₂O and NaVO₃-HClO₄-Cd(OAc)₂-H₂O was studied. Cd(VO₃)₂.4H₂O is predominantly formed in both systems at 20°C. Under certain conditions, even Na₄CdV₁₀O₂₈.24-26H₂O arises in a system contg. AcOH. With increasing temp. of the solns., the equil. is shifted towards formation of less condensed vanadate ions, which manifests itself in increasing content of Cd₂V₂O₇ in the solid product.
