Zorluk: OrtaDefinitions and Theories of Acids and Bases

Complete the following statement regarding acid-base behavior according to the Brønsted-Lowry theory.

Cevap:In the reversible reaction HSO4−+H2O⇌SO42−+H3O+HSO_4^- + H_2O \rightleftharpoons SO_4^{2-} + H_3O^+, the species that acts as the conjugate base of hydrogen sulfate ion (HSO4−HSO_4^-) is the 【sulfate】 ion.

Cevap

sulfate (or tetraoxosulfate(VI), SO42−SO_4^{2-})
Under the Brønsted-Lowry definition, an acid is a proton donor and its conjugate base is the species remaining after the loss of that proton. When the hydrogen sulfate ion (HSO4−HSO_4^-) donates a proton (H+H^+), it forms the sulfate ion (SO42−SO_4^{2-}), making sulfate the conjugate base.

Adım Adım Çözüm

1
Identify the Brønsted-Lowry acid in the forward reaction.
The hydrogen sulfate ion (HSO4−HSO_4^-) acts as an acid by donating a proton (H+H^+).
By definition, a Brønsted-Lowry acid is a proton donor.
2
Determine the remaining species after proton donation.
Removing H+H^+ from HSO4−HSO_4^- yields SO42−SO_4^{2-}.
When an acid loses a single proton, the remaining chemical species formed is its conjugate base.
