Аннотация:On the basis of structural and pH-metric titration data for suspensions of hydrated zirconium, hafnium, tin, and lead dioxides, it is demonstrated that the acidic properties become weaker while the basic properties become stronger in the sequence Hf-Zr-Sn-Pb. The dependence of these properties on the temperature of the sample pretreatment was revealed.
