Vedclass · Accepted Answer

Disodium salt of $EDTA$

Vedclass · Answer

(B) The disodium salt of $Ethylenediaminetetraacetic$ $acid$ $(EDTA)$ is used for the complexometric titration of metal ions like $Ca^{2+}$ and $Mg^{2+}$ to determine water hardness.In this titration,an indicator $(D^{3-})$ forms a red metal-indicator complex with $M^{2+}$ ions.$i.$ $M^{2+} + D^{3-} \rightarrow [MD]^{-}$ (Red complex)$ii.$ $[MD]^{-} + EDTA^{4-} \rightarrow [M(EDTA)]^{2-} + D^{3-}$ (Blue free indicator)The $EDTA$ forms a more stable complex with the metal ions,displacing the indicator and causing a color change from red to blue at the endpoint.

Which reagent is commonly used for the determination of water hardness by titration?
