Answer:
a. HF (aq) ["Bronsted-Lowry acid"]
H₂O (l) ["Bronsted-Lowry base"]
b. HCO₃⁻ (aq) ["Bronsted-Lowry base"]
H₂O (l) ["Bronsted-Lowry acid"]
Explanation:
Bronsted Lowry theory expose this:
Acid is the one that release a proton
Base is the one that accept a proton
a. HF (aq) + H₂O(l) → H₃O⁺ (aq) + F⁻ (aq)
HF is the acid, it donates the proton to water.
Water is the base, it accepts the H⁺
b. HCO₃⁻ (aq) + H₂O (l) → H₂CO₃ (aq) + OH⁻(aq)
Anion bicarbonate is the base because it accepted the H⁺ from the water, which is the acid.
