Answer the following question given this paragraph: 

Transition-metal fluorides usually have higher oxidation states than their iodides. For a given metal, the lowest-oxidation-state oxide is basic and the highest-oxidation-state oxide is acidic. Halides of the transition metals become more covalent with increasing oxidation state and are more prone to hydrolysis. Propose a method to prepare each of the following compounds: TiCl 4[(CH3)2O]2, Na2TiO3, V2O5, and Na2Cr2O7. Of the group 5 elements, which.


Q: Halides of the transition metals become more covalent with increasing oxidation state and are more prone to what?


A:
hydrolysis
