In the Brønsted-Lowry definition of acids and bases, a conjugate acid-base pair consists of two substances that differ only by the presence of a proton (H⁺). A conjugate acid is formed when a proton is added to a base, and a conjugate base is formed when a proton is removed from an acid. View more lessons or practice this subject at www.khanacadem...

Helped me a lot! Thank you!!

[@3runjosh]

in my textbook it says: HCl, H2O is not a base pair?
But HCl becomes Cl giving away it's H+ to become H3O and Cl. Then you can Give away that H3O proton to become H2O and HCl again. Apparently that is wrong though?

[@tajklair]

THIS IS ONE VIDEO EVER THAT I ACTUALLY UNDERSTOOD WHAT WAS GOIGN ON

[@yogurtfluff1]

There's n mention who the narrator was but whoever she was she seemed a little nervous but otherwise seems very good at explaining complicated concepts.

Wait I thought elements can lose electrons but not protons???

[@suramasahoo5920]

The H+ ion is the proton in this case......

[@Hatmaster]

@@suramasahoo5920 ah that makes sense thanks

[@bhupeshsarmal2854]

Thats basically ionic concept ,more about ionic compounds ,so when they are dissociated into its ions ,this is what happens next !
