I do not understand the
acid + base >conjugate base + conjugate acid
Please explain it to me with an example. I really do not understand it and I truly need your help.
I do not understand how he hydrogens transfer and stuff like that.
Your help is very much appreciated!
Thanks

The one with more H atoms in the acid; the one with fewer H atoms is the conjugate base.
H2AsO4^ + H2O ==> H3O^+ + HAsO4^2
H2AsO4^ has more H atoms than the HAsO4^2; therefore, the first is the acid and the second one the conjugate base.
For the H2O/H3O^+ pair,
H2O is the base and H3O^+ the conjugate acid. H2O has the fewer H, H3O^+ more. It's really that simple.
