The number of equivalents of $Na_{2} S_{2} O_{3}$ required for the volumetric estimation of one equivalent of $Cu^{2 +}$ is:

Answer:

Solution:

In iodometric titration, 2 equivalents of Na₂S₂O₃ react with 2 equivalents of Cu²⁺. Thus, 1 equivalent of Cu²⁺ requires 1 equivalent of Na₂S₂O₃.

The final answer is $1$
