Question

Which will make basic buffer? A. 100 mL of 0.1 M HCl + 100 mL of 0.1 M NaOH B. 50 mL of 0.1 M NaOH + 25 mL of 0.1 M CH3COOH C. 100 mL of 0.1 M CH3COOH + 100 mL of 0.1 M NaOH D. 100 mL of 0.1 M HCl + 200 mL of 0.1 M NH4OH Select the correct answer from above options

Answer 1

Correct Answer - D Acid-base titration HCl 10 m mole + Na4OH 20 m mole 20-10 → Na4Cl 10 m mole HCl is limiting reagent Solution contain NH4OH (WB) & NH4Cl (SAWB) The basic buffer will form
