# Why does bih3 act as a reducing agent? [closed]

I do understand that the bi-h bond is weak....... And it releases hydrogen easily..... I'm just confused with which type of hydrogen..... Does it release a h+ or a h2? I'm pretty sure h+ can only act as an oxidising agent since it'd already lost it's proton... So I'm gonna assume it releases a h2.... But I was also taught that h2 can act as both an oxidising and a reducing agent.... Why can't it go the other way around?? Why can't it act as an oxidising agent ....
