Answer:
Explanation:
A Brönsted-Lowry acid is defined as any substance that has the ability to lose, or "donate a proton" [H +].
A Brönsted-Lowry base is a substance capable of gaining or "accepting a proton" [H +].
Then a proton transfer occurs, which requires the presence of a proton donor, that is, an acid and a base that accepts them.
This theory has the disadvantage of leaving out several substances that are acidic and that do not have protons.
Thiocyanic acid is a chemical compound that can be considered, but not a Bronsted Lowry base, giving up the proton and generating the anion [SCN] -
Chemical reaction of PO₄³⁻ ion in water:
PO₄³⁻(aq) + H₂O(l) → HPO₄²⁻(aq) +OH⁻(aq).
Kb = [HPO₄²⁻] · [OH⁻] / [PO₄³⁻]; <span>base ionization constant.
</span>Base ionization constant <span>is the equilibrium </span>constant<span> for the </span>ionization<span> of a </span>base<span>.
</span>According
to Bronsted-Lowry theory acid are donor of protons and bases are
acceptors of protons (the hydrogen cation or H⁺<span>).
</span>PO₄³⁻ is Bronsted base and it can accept proton and
become conjugate acid HPO₄²⁻.
