What volume of 0.1 M NaOH reacts with 200 mL of 0.05 M phenol? (C6H5OH + NaOH → C6H5O⁻Na⁺ + H2O)
Q1. What volume of 0.1 M NaOH reacts with 200 mL of 0.05 M phenol? (C6H5OH + NaOH → C6H5O⁻Na⁺ + H2O)
Answer: 100 mL
Explanation: Moles of phenol = 0.05 × 0.2 = 0.01 mol. 1:1 ratio. Volume = 0.01 / 0.1 = 0.1 L = 100 mL. Option A uses half the volume.
