Students often are confused by Bronsted=Lowry acid/base theory but here is an easy way to remember it. Look at ANY pair. The acid will be the one with more H atoms. Bases will be the one with the smaller number of H atoms.
From above:
Write the formulas of the conjugate bases of the following Brønsted-Lowry acids.
A.HCN
B.(CH3)2NH2+
C.H2SO4
D.HSO4−
So for A we take the H off and have CN^-.
For B. so we take off the H (from the N) to leave (CH3)2NH
For C, take H off to leave HSO4^-
etc.
For the second part add the H to find the acid.
Write the formulas of the conjugate acids of the following Brønsted-Lowry bases.
A.C4H4N−
B.(SO4)2−
C.(CH3)3N
