Step 1:I'll solve this step-by-step following the specified LaTeX and formatting guidelines:
Step 2:: Understand the Concept of Conjugate Base
A conjugate base is formed when an acid loses a proton (H⁺). To find the conjugate base, we need to remove one hydrogen from the given species.
Step 3:: Analyze the Starting Species
The starting species is $$HPO_{4}^{2-}$$, which is the hydrogen phosphate ion.
Step 4:: Remove a Hydrogen Proton
By removing one H⁺ from $$HPO_{4}^{2-}$$, we get:
PO_{4}^{3 -}
Step 5:: Verify the Charge
- New species charge: $$2- - (1+) = 3-
- Removed proton (H⁺) has a charge of 1 +
Final Answer
- Formula: PO_{4}^{3 -} - Net Charge: 3 - The conjugate base of HPO_{4}^{2 -} is the phosphate ion PO_{4}^{3 -}.
