Answer:
you dony have a picture for me to match them
Explanation:
Answer:
d) PO4^3-, HPO4^2-
Explanation:
Basically, an acid and a base which differs only by the presence or absence of proton (hydrogen ion) are called a conjugate acid-base pair.
a) HI, I
This is incorrect. For the acid, HI the conjugate base is I⁻ ion.
b) HCHO2, SO4^2-
This is incorrect, there's no relationship between both entities.
c) CO3^2-, HCI
This is incorrect, there's no relationship between both entities.
d) PO4^3-, HPO4^2-
This is correct. The difference between both entities is the Hydrogen ion. This is the conjugate acid-base pair

Explanation:
Hello!
In this case, since the main molecular reaction that is taken place in the beaker is:

In such a way, we understand that one breaker contained silver nitrate and the other one barium iodide. Thus, the complete molecular equations turns out:

Now, for the complete ionic equation, we just ionize the aqueous species:

Finally, for the net ionic equation we cancel out barium and nitrate ions as the spectator one because they are both sides on the equation:
