For the species HSO ₄⁻ and NH ₃ their conjugative acids respectively are
Options
- ASO ₄^2 and NH ₄⁺
- BSO ₄^2 and NH ₂
- CH ₂ SO ₄ and NH ₄⁺
- DH ₂ SO ₄ and NH ₂
Correct answer
C. H ₂ SO ₄ and NH ₄⁺
Step-by-step solution
A conjugate acid, within the Bronsted Lowry acid base theory, is a chemical compound formed when an acid donates a proton ( H ⁺ ) to a base. In other words, it is a base with a hydrogen ion added to it, as in the reverse reaction it loses a hydrogen ion. Thus, conjugate acid of HSO ₄⁻ is H ₂ SO ₄ and conjugate acid of NH ₃ is NH ₄⁺ . Hence, the correct option is (3).
