What is the conjugate acid of H2PO4-? (Type your answer using the format format [H2PO4]- for H2PO4-
What is its conjugate base?
i have no cluee
thanks
If you want the H2PO4^- to be a base, it must accept a proton; therefore,
H2PO4^- + H3O^+ ==> H2O + H3PO4
and DrBob222 is why you should never trust the internet
To determine the conjugate acid and conjugate base of a given compound, it is helpful to understand the concept of acids and bases.
Acids are substances that can donate a proton (H+) to a reaction, while bases are substances that can accept a proton. The conjugate acid of a base is formed by adding a proton to the base, while the conjugate base of an acid is formed by removing a proton from the acid.
In this case, H2PO4- is a base because it can accept a proton. To find its conjugate acid, you simply add a proton to the base. The resulting compound is H3PO4, also known as phosphoric acid. Therefore, H3PO4 is the conjugate acid of H2PO4-.
Similarly, the conjugate base of an acid is formed by removing a proton from the acid. In this case, we start with phosphoric acid (H3PO4) and remove a proton to form H2PO4-. Hence, H2PO4- is the conjugate base of H3PO4.
In summary:
- The conjugate acid of H2PO4- is H3PO4 (phosphoric acid).
- The conjugate base of H3PO4 is H2PO4-.
