Question

The volume of 0.1M H2so4 required to meutrilize complete 40ml of 0.2M naoh solution is?

Answer 1

80 mL is the correct answer

Step - by - step Explanation: MV = M'V' where each terms stands for,

• M = Molarity (in M)
• V = Volume (in mL)

→ 0.1 M × V = 0.2 M × 40 mL

→ 0.1 V = 8

→ V = 8/0.1 or 80/1

→ V = 80 mL

Hence 80 mL is needed to neutralize 40 mL of Sodium Hydroxide solution.
