Q: The conjugate acid of HASO₄²- is-
  • A.
    option image
  • B. ASO₄⁺
  • C. H₃ASO ₄
  • D.
    option image
Correct Answer: Option B - The conjugate acid of a species is formed when it gains a proton (H⁺). In this case HASO₄²⁻ gains a proton to become H2ASO₄⁻ making it the conjugate acid.
B. The conjugate acid of a species is formed when it gains a proton (H⁺). In this case HASO₄²⁻ gains a proton to become H2ASO₄⁻ making it the conjugate acid.

Explanations:

The conjugate acid of a species is formed when it gains a proton (H⁺). In this case HASO₄²⁻ gains a proton to become H2ASO₄⁻ making it the conjugate acid.
