why does vanadium have maximum observed oxidation state of +5 while for Co the maximum observed oxidation state is +3? why are solutions of chromium(2) acidic? 
Why does vanadium have maximum observed oxidation state of +5
Click For Summary
SUMMARY
Vanadium exhibits a maximum observed oxidation state of +5 due to its electronic configuration and the stability of its +5 oxidation state in various compounds. In contrast, cobalt's maximum oxidation state is +3, attributed to its electron configuration and the stability of its lower oxidation states. Additionally, chromium(II) solutions are acidic because chromium forms hydroxy complexes that hydrolyze water, releasing H+ ions. This discussion highlights the differences in oxidation states among transition metals, specifically vanadium, cobalt, and chromium.
