Determine the weaker base between the two. Explain why.
HO⁻ or Cl⁻

• A. HO⁻_;It is the weaker base because its corresponding acid (H₂O) is stronger.
• B. Cl⁻;It is the weaker base because its corresponding acid (HCl) is stronger.
• C. Neither of the two;The two conjugate bases are similar in strength since the atoms bonded to H (of the corresponding acids H₂O and HCl) are both electronegative.
• D. Neither of the two;The two conjugate bases are similar in strength since their corresponding acids (H₂O and HCl) are strong.

Answer: (B)
