It is an acidic buffer.
For acidic buffer,
Which will make basic buffer? [2019]
100 mL of 0.1 M HCl + 100 mL of 0.1 M NaOH
50 mL of 0.1 M NaOH + 25 mL of 0.1 M
100 mL of 0.1 M + 100 mL of 0.1 M NaOH
100 mL of 0.1 M HCl + 200 mL of 0.1 M

Acid-base titration:
HCl is the limiting reagent.
Solution contains (weak base) and (salt of strong acid and weak base). Therefore, a basic buffer will be formed.
