Homework Help: Chemistry Logic

Posted by Taasha on Friday, August 3, 2007 at 7:13pm.

How can I tell a conjugate base from a regular base and a conjugate acid from a regular acid? For example, in:

H2O + HONH3 (reversible arrows) HONH2 + H3O+

What is the acid, base, conjugate base, conjugate acid? Is there no base and conjugate base since HONH3 is an acid?

The H2O accepted a proton to become H3O^+; therefore, H2O must be a base and the H3O^+ is the conjugate acid.
HONH3 donated a proton so HONH3 must be the acid and HONH2 is the conjugate base. Check my thinking.
