Question

Which of the following solutions is a buffer?A) A solution made by mixing 100 mL of 0.100 M HClO and 50 mL of 0.100 M HCl.B) A solution made by mixing 100 mL of 0.100 M HClO and 500 mL of 0.100 M NaOH.C) A solution made by mixing 100 mL of 0.100 M KClO and 50 mL of 0.100 M KCl.D) A solution made by mixing 100 mL of 0.100 M HClO and 50 mL of 0.100 M NaOH.

Answer 1

Answer:

D

Explanation:

solution made by mixing 100 mL of 0.100 M HClO and 50 mL of 0.100 M NaOH Can resist pH change when there is little addition of either acid or base, hence it is a buffer solution
