HW 12.3

Postby Haocheng Zhang 2A » Mon Dec 04, 2017 11:18 pm

The answer says the conjugate base of H2SO4 is HSO4-. I wonder whether SO4 2-is also the conjugate base of H2SO4 or it is the conjugate base of HSO4-. I remeber in high school I was told conjugate pair can only have the difference of one hydrogen.

I believe what you learned in high school was right. A conjugate base should only have the different of one hydrogen

SO4 2- is the conjugate base of HSO4- because, as stated above, the difference is only a single hydrogen. When finding the conjugate base of something, remove a single hydrogen and add a negative charge, hope this helps!

For instance if you have NO3- the conjugate acid would be HNO3, but if you have the weak base NH3 then you will have the conjugate acid ammonium which is NH4+. just remember for conjugate base minus one H and for the conjugate acid add one H.
