Step 1:I'll solve this step-by-step using proper acid-base chemistry principles:
Step 2:: Understand the Concept of Conjugate Acids
- A conjugate acid is formed when a base accepts a proton (H+) - To find the conjugate acid, we need to add a proton (H+) to the given species HCO^3 -
Step 3:: Add a Proton to HCO^3 -
- When we add a proton to HCO^3 -, we get H^2CO^3 - This means H^2CO^3 is the conjugate acid of HCO^3 -
Step 4:: Verify the Chemical Reaction
HCO3^{-} + H^{+} \rightarrow H_{2}CO_{3}
Step 5:: Analyze the Given Options
A. CO3^{2 -} - This is a base, not the conjugate acid B. H^2CO^3 - This is the correct conjugate acid C. CO^2 - This is a neutral molecule, not the conjugate acid D. H^2O - This is a different molecule
Final Answer
H^2CO^3 is the conjugate acid of HCO^3 -.
