A Lewis acid is the substance which can accept lone pair of electron and a Lewis base is the substance which can donate lone pair of electron.
In given question H+ ion takes lone pair of electron from phosphorus and form bond. So H+ is the Lewis acid and PPh₃ is the Lewis base.

Using the Lewis concept of acids and bases, identify the Lewis acid and base in each of the following reactions: Ni(NO3)3(s)+6H2O(l)→Ni(H2O)63+(aq)+3NO3−(aq) Can someone explain to me why Ni(NO3)3 is a lewis acid if it's accepting h2o and why h2o is a lewis base if it's giving itself instead of receiving an e-? CH3NH2(g)+HBr(g)→CH3NH3Br(s) Can someone also explain to me why HBR is a lewis base it's donating a H+? And why CH3NH2 is a lewis acid for accepting a H+?...
