A solution containing 1 go of the complex
`[Cr(H_(2)O)_(5)CI]CI_(2)H_(2)O` was passed through a cation exchanger The acid liberated was made up to 1 litre Calculate the strength of acid solution (`Aw of Cr=52` and Mw of complex `= 266.5 g mo1^(-1)` .

Text Solution

Verified by Experts


`Mw` of the complex `=266.5g"mo1"^(-1)`
`266.5g` of complex gives implies `2"mo1"` of `HCI//Limplies2xx 36.5g`
`1g` of the compex gives `implies(2 xx 36.5)/(266.5)implies 0.2737g L^(-1)`
Hence strength of `HCI` solution `= 0.2737gL^(-1)` .
