ANSWER:
Solution 34P
Here in each equation, we have to label the acids, bases, and conjugate pairs:
According to the Bronsted-Lowry concept, an acid will always form its conjugate base (CB) by donating a proton and a conjugate acid (CA) is always formed by a base by gaining a proton.
In general, the dissociation of an acid in aqueous medium is given below,
HA + H2O ⇄ H3O+ + A-
Acid base CA CB
Step 1
(a) NH3 + H3PO4 ⇄ NH4 + + H2PO4-
The equation labeled with acid, base and their conjugate pair is given below,
