A substance that has a pH greater than 7 in aqueous solution
B
A substance that donates a proton () to another species
C
A substance that produces ions when dissolved in water
D
A substance that accepts a proton () from another species
Verified step by step guidance1
Recall the Brønsted–Lowry acid-base theory, which defines acids and bases based on proton transfer.
Understand that in this theory, an acid is specifically defined as a substance that donates a proton (H\(\textsuperscript{+}\)) to another species.
Recognize that a base, conversely, is a substance that accepts a proton (H\(\textsuperscript{+}\)) from another species.
Note that pH values and the production of specific ions like O\(\textsubscript{2}\)\(\textsuperscript{−}\) are not part of the Brønsted–Lowry acid definition but relate to other concepts or definitions.
Therefore, the correct identification of a Brønsted–Lowry acid is a substance that donates a proton (H\(\textsuperscript{+}\)) to another species.
