Question

Why sodium thiosulphate is usedfor titration in DO?

Answer 1

$\huge{\underline{\underline{\color{darkblue}{\bf{♡Answer♡}}}}}$

Redox titration using sodium thiosulphate, Na2S2O3 (usually) as a reducing agent is known as iodometric titration since it is used specifically to titrate iodine. This absorption will cause the solution to change its colour from deep blue to light yellow when titrated with standardised thiosulfate solution
