Q55 / 180 · NEET 2019 (All India) · Chemistry

Which will make basic buffer?

  • A
    50 mL of 0.1 M NaOH+25 mL of 0.1 M CH3COOH
  • B
    100 mL of 0.1 M CH3COOH+100 mL of 0.1 M NaOH
  • Correct answer
    C
    100 mL of 0.1 M HCl+200 mL of 0.1 M NH4OH
  • D
    100 mL of 0.1 M HCl+100 mL of 0.1 M NaOH

Solution

Given,

100 ml of 0.1 M HCl+200 ml of 0.1 M  NH4OH

Figure

Therefore, it is a basic buffer.

Hence, option (C) is correct.

Hence, the correct answer is option: 'C'.
