I feel that this board is so desolate. I'd like to share an interesting reaction copied from my textbook as another problem for this week. Does anybody want to have a try?

Is PH=3 triphenylphosphine?
Logged
Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3.

Sorry I'm not good at English so I cann't decribe it very well by words.
Well, "1)H2SO4, H2O,PH=3; 2)48%HBr, H2O", understand?

It is not clear whether PH=3 means pH=3 or is some kind of pseudostructural symbol describing presence of reagent.

I didn't think that my question would be so obscure.
