Verified step by step guidance1
Recall that in the Brønsted–Lowry acid-base theory, a conjugate acid is formed when a base gains a proton (H\textsuperscript{+}).
Identify the given base: the sulfate ion, which is \$\mathrm{SO_4^{2-}}\$.
To find the conjugate acid, add one proton (H\textsuperscript{+}) to the sulfate ion, increasing its hydrogen count by one and reducing its negative charge by one.
Write the formula of the conjugate acid by adding H\textsuperscript{+} to \$\mathrm{SO_4^{2-}}\$, resulting in \$\mathrm{HSO_4^-}\$.
Understand that \$\mathrm{HSO_4^-}\$ is called the bisulfate ion, which is the conjugate acid of the sulfate ion in the Brønsted–Lowry model.
