Sorry for the wait.. I hope I got them all right :)
The acid is H2Se, the base is H2O, the conjugate acid is H3O+, the conjugate base is SeH–.
The reaction equation is as follows;
H2Se + H2O → SeH– + H3O+
The acid is the specie that donates a proton while the base is the specie that <em>accepts</em> the proton.
The specie formed from the acid after it donates a proton is called the conjugate base while the specie formed from the base after accepting a proton from the acid is called the conjugate acid.
From the reaction equation, we can see that the acid is H2Se, the base is H2O. The conjugate acid is H3O+ while the conjugate base is SeH– .
