Question

multiple choice 2 points the conjugate acid of so₄²⁻ is ______. h₃so₄⁺ hso₄⁻ oh⁻ hso₄²⁻ h₂so₄

Explanation:

To find the conjugate acid of a base, we add a proton ($\ce{H+}$) to the base. For $\ce{SO4^{2-}}$, adding $\ce{H+}$ gives $\ce{HSO4-}$ (since $2 - 1 = 1$ for the charge).

Answer:

B. $\ce{HSO4-}$
