JEE Main 2018 — Coordination Compounds Question with Solution
JEE Main 2018 (16 Apr Online)
Question
In a complexometric titration of metal ion with ligand end point is estimated spectrophotometrically (through light absorption). If 'M' and 'C' do not absorb light and only 'L' absorbs then the titration plot between absorbed light versus volume of ligand 'L' would look like:

Correct answer
A
Step-by-step explanation
Initially ligand consumed by metal due to formation of complex. So absorbed light remain constant, after complex formation is completed, extra volume of ligand solution increases ligand concentration and also increases absorbed light.
